Kyle Long said he was "embarrassed" by the Chicago Bears' running game in Week 2. Marc Trestman called it "very poor."

Facing a 17-point deficit against the San Francisco 49ers, the Bears had to look to pass more, but when they did run it wasn't pretty with Matt Forte rushing for just 21 yards on 12 carries. A week earlier, Forte was effective with 82 yards in Week 1 against the Buffalo Bills, but he got just 17 carries.

It doesn't get any easier in Week 3 against the New York Jets, who have allowed the fewest rushing yards (105) in the NFL this season. Is there reason to be concerned about the Bears' running game or is it all part of the game plan from week to week? Our panel weighs in on that and more:

Fact or Fiction: The Bears' running game is a concern after two weeks.

Jeff Dickerson: Fact. Forte is an elite tailback. There is no issue with him. But Long labeled the Bears' effort in the run game "embarrassing" against San Francisco. That sounds a tad extreme. However, Forte only gained 21 yards on 12 carries on Sunday night. The best run came when Jay Cutler scrambled for 25 yards, so I think it's OK to call it concerning. But there's no reason to panic. Keep in mind, the Bears aren't exactly a power running team. They rely more on running outside the tackles with Forte. The ground game isn't the bread and butter of the offense. The Bears are a pass-first team. That's just the way it is. Also, fullback Tony Fiammetta hasn't been available yet this season due to injury and a release before re-signing. Maybe Fiammetta helps when he's on the field against the Jets roughly 15-20 percent of the time.

Jon Greenberg: Fiction. It's just the way it is. I don't think Trestman is ever going to call a completely balanced game, run-pass wise. It'll always be slanted toward the pass with Cutler. After the opening loss against Buffalo, I asked Forte if he wanted more touches, and he admitted 17 carries was a little low, but that he'll get his touches on short passes ("extended handoffs"). He caught eight passes against the Bills. Those numbers dropped to 12 and 5 against the Niners. I'd like to see the Bears get more creative on runs -- San Francisco showed a few cool wrinkles Sunday night -- and more importantly, give him a few drives where he can really carry the load. Too often he was running on first down, getting stuffed because it was so obvious, and then the Bears went to the pass. But there were drives where they really tried to get him the ball. In the 13-play, 80-yard drive that spanned the third and fourth quarters, he touched the ball six times, four passes and two runs. But he only gained 18 yards, 11 coming on one pass. Long said he was frustrated in their run-blocking, so maybe Trestman was wise to spread the wealth.

Fact or Fiction: Charles Tillman is the best defensive back in Bears' history.

Jeff Dickerson: Fact. It's a close race between Tillman (two Pro Bowls) and legendary safety Gary Fencik (two Pro Bowls). Fencik holds the franchise record with 50 takeaways (38 interceptions, 12 fumble recoveries) and won a championship in 1985. Tillman is the Bears' all-time leader in defensive touchdowns (nine), interception return yards (675), interception return touchdowns (eight), and ranks third with 36 career picks. However, Tillman revolutionized the game with his uncanny ability to force fumbles from the cornerback position. The "Peanut Punch" has been responsible for 42 forced fumbles since 2003, the second-highest total in the league over that span. Tillman changed the way coaches teach the game to younger players. Tillman gets the nod, in my opinion. But Fencik is underrated in terms of what he provided the Bears' defense in the mid-70s to late 80's.

Jon Greenberg: Fact. It's so tough to judge between eras, but given Tillman's singular effect on the defense -- his ability to create takeaways -- and his team records in interception return yards, defensive touchdowns and interceptions returned for touchdowns, let's agree to call him that. Add to that, his 36 interceptions and 42 forced fumbles, he's got a great case. Tillman's had a fantastic career, if it's over.

Fact or Fiction: There won't be much of a dropoff on the defense with rookie Kyle Fuller replacing Tillman.

Jeff Dickerson: Fiction. Fuller looks ready to assume a full-time starting role. He belongs. But rookies always experience a certain degree of growing pains when pressed into action straight out of college. That especially holds true at the cornerback position where players are taught to have short memories. The Bears play in a division with Calvin Johnson and Aaron Rodgers. I don't care how ready a player is, the Packers and Lions can throw the football. Fuller will be tested. I believe he will hold up OK, but let's hold off on the Tillman comparisons. Fuller will be making his first career NFL start on Monday night. Tillman made 158, including the postseason. Maybe Fuller eventually becomes the next Tillman. But it doesn't happen overnight. Give the rookie time.

Jon Greenberg: Fiction. That's tough to say after two games. Check out the Bears' schedule, Fuller will have some difficult receivers to cover if the Bears throw him to the wolves and Megatrons of the league. The Bears are lavishing praise on him, and his two-pick game against the Niners augur good things to come. Fuller looks like an All-Pro, and he's got young legs, but while Tillman was getting older, experience is often a cornerback's greatest weapon. Tillman had seen it all and his instincts let him gamble for those punch-outs. The Bears would be better off with three strong cornerbacks.

Fact or Fiction: Special teams will cost the Bears at least one win this season.

Jeff Dickerson: Fact. This has been a problem since the summer. The Bears just don't seem talented, organized, or intelligent enough on special teams. They were lucky to avoid a complete meltdown after the 49ers' blocked punt led to an early touchdown. Next time, they may not be so fortunate. In the past, the Bears used to make their special teamers into positional backups. Now, the Bears try to make their positional backups into special teamers. The philosophical shift is partly to blame for the decline. Losing players such as Devin Hester, Craig Steltz, Eric Weems, Blake Costanzo, Zack Bowman, Anthony Walters and Jordan Senn hurts. I think it's fair to say coordinator Joe DeCamillis needs to do the best coaching job of his career to turn it around. DeCamillis has 26 years of experience coaching special teams in the NFL. This is probably one of his toughest assignments to date.

Jon Greenberg: Fact. This group is awful. Disorganized and sloppy. Whither Dave Toub? Oh yeah, he's in Kansas City. It's not just coaching, it's the caliber of players in the group, and that's on GM Phil Emery and the coaches. The Bears cut Shaun Draughn after he committed two penalties on special teams and missed a block that led to a blocked punt. So it's not like the Bears aren't aware of the problem. So yeah, unless they can find some players on special teams, I think they could lose a game because of it.
