DALLAS -- The Dallas Mavericks were convinced that Dwyane Wade barreled right through Brian Cardinal's chest on that first-quarter drive. So they naturally screamed for a charging call.

In retrospect?

Let's just say that the starving home team -- once all of its ringless vets got past their fury over Cardinal getting called for blocking -- wound up getting so much more than the whistle it wanted.

Because of that early collision, Wade had to make two trips to the locker room for treatment in what LeBron James had openly called the "biggest game of my life." Because of the damage that tangle did to Wade's left hip, Dallas never had to deal with the defense-shredding slasher who, until this Game 5, looked hauntingly like the relentless younger model who had wrecked the Mavericks in 2006.

The Mavs' longtime tormentor mustered 23 points Thursday night, including a huge late 3-ball that briefly seized crunch-time control, but this D-Wade was guardable. This was a D-Wade whom the home team could handle, because Dallas also finally found more to throw at the Miami Heat than Dirk Nowitzki.

The biggest game of LeBron James' life didn't belong to LeBron -- not even close -- and this D-Wade couldn't bail his buddy out, either. It might have taken the Mavericks all night to get there, but they ultimately capitalized on Wade's limitations and a fourth successive fourth-quarter abdication in this series for the self-styled King James to seize a 112-103 triumph filled with Dallas heroes for a change.

With a compromised Wade and a hollow triple-double from James, Miami couldn't keep up with the Mavs' long-awaited offensive breakout. The Heat couldn't withstand the 13 3-pointers that fell one short of a Finals record, four more double-digit scorers besides Nowitzki's 29 points or the sight of Jason Terry (eight of his 21 points in the final 3:23) stepping into the late-game breach to spare Dirk from his usual daunting load at closing time.

The Heat thus limp back home praying that their closer absorbed no lasting damage from the Cardinal crash, since James has given zero indication that he's capable of filling that dominance void. After all those vows to redeem himself from his eight-point misery in Game 4, LeBron looked like a shooter with zero faith in his jumper while managing just two free-throw attempts in nearly 46 minutes and finishing with a lowly two points in Game 5's final period.

Cardinal's 9 minutes, 37 seconds of playing time were no less memorable.

"He's really a unique player," Dallas coach Rick Carlisle said of Cardinal, who gave himself a shot to be remembered -- even if that wasn't the intention as he slid into charge-taking position -- as the first Mav who's managed to stop (or maybe just slow) Wade.

"He's always going to be there taking charges," Carlisle continued. "He's always going to be making contact with people. He's going to be there."

Two games ago, Cardinal wasn't even in Carlisle's rotation. Now he's a fixture after Carlisle responded to Miami's Game 3 win here by moving J.J. Barea into the starting lineup (in place of DeShawn Stevenson) and letting Peja Stojakovic know that Cardinal was going to start getting the first crack at the few minutes available during Nowitzki's rests.

Now look. Barea backed up Terry with 17 points of his own, matching Mario Chalmers' latest haul of four 3s for the Heat. Jason Kidd threw in 13 points, including a bigger late 3 than Wade's, after going scoreless Tuesday night. Cardinal, meanwhile, left such an impression with his scrappiness in that 9:37 stint that Stojakovic, on his 34th birthday, could be seen on the Mavs' bench serving up some of the heartiest congratulatory slaps for the effort.

"It looked like a Mavericks game," said center Tyson Chandler, referring not only to the 112 points on the scoreboard but the Dallas rally in the final 4:37.

Said Carlisle: "Persistence is our game. We're an old-school team. We're not high-fliers. ... Our game is near the ground. We have to play with brains and guts."

Nowitzki remembers how annoyingly pesky Cardinal can be when he's on the other side. Dirk has been known to tell the story of how he once tried to dismiss the dude in the Minnesota uniform hounding him, as they lined up for a free throw when Cardinal was still with the Wolves, by saying: "How are you still in this league?"

They've since become so close that Cardinal is a frequent attendee at Nowitzki's dinners on the road. "One of my favorite teammates of all time," Dirk said earlier this week.

The Heat potentially have two games left to prove that they can match the Mavs' togetherness, or else Dallas will win a first championship that would mean redemption galore for the likes of Nowitzki, Kidd, Terry and ghostly silent Mavs owner Mark Cuban. Miami's problem is that the Mavs, in these past two wins, have become a T-E-A-M again, looking more like the group that swept the Los Angeles Lakers and schooled Oklahoma City with varied doses of help to supplement the hottest two months of Nowitzki's career.

"We always said: When [Terry] plays well, they're very tough to beat," said James, whose 17 points, 10 rebounds and 10 assists could not mask his run of misfires -- or the two 3s that Terry lofted over him -- after Wade's triple and subsequent scowl had staked Miami to a 99-95 lead.

Said Heat forward Chris Bosh, pinpointing one key to Miami's strategy after seeing Dallas score 15 of the evening's final 18 points: "They can't have [other] guys more than Dirk have a good game."

The hungry, hungry home team indeed hurt the Heat with variety in the season's final game to be staged in Big D. An example: Terry, Nowitzki and Barea all connected with fortuitous heaves from beyond the 3-point line -- Terry more than once -- to more than cancel out another Chalmers buzzer-beater at the end of the first quarter.

As for how badly Wade is hurt heading into Sunday, Heat coach Erik Spoelstra said: "Way too early [to know]. We'll have to see how it responds tomorrow. When he's able to sweat and keep it warm, he was fine. Fortunately we have an extra day. We'll see if that's enough."

Wade had even less to share beyond insisting that Spoelstra, James and the rest of the Heat have nothing to worry about when it comes to Game 6. He actually volunteered more about the Mavs than his limp, refusing to expound on an injury that -- despite no hip contact with Cardinal on available replays -- forced Wade to miss the start of the second half.

"Obviously, they're a tough team to guard," Wade said. "They're the best offensive team in this game."

One more win and, for 2010-11 purposes at the very least, Dallas can strike the word offensive from that sentence.
