ALLEN PARK, Mich. -- A daily review of the hot topics coming out of Detroit Lions training camp:

• Rough day for the first-team offense during a two-minute drill situation. Defensive ends George Johnson and Darryl Tapp -- neither of whom is expected to be a first-team defender this season -- had touch sacks of Matthew Stafford. Stafford and the offense also went three-and-out on one possession with the quarterback being forced to throw away multiple passes when no one was open. Not surprisingly, Ndamukong Suh was also causing havoc up the middle. The second team fared better, scoring a touchdown and having Giorgio Tavecchio also make a 41-yard field goal to close practice. Jim Caldwell didn't seem too concerned, though, with any of the issues the first-team offense was having.

• Why not? Well, the first-team offense still has Calvin Johnson, who made two exceptional catches Friday to show why he is the top receiver in the game. He grabbed a touchdown in 7-on-7 after the play was whistled dead, but the way he plucked it was exceptional. There was another play in which a Stafford pass looked like it was headed nowhere, then Johnson came out of his break, dove perfectly on the low ball and caught the ball in front of Chris Greenwood in 11-on-11. It was one of those plays that no defensive back can do anything about. And that has nothing to do with Greenwood, as other cornerbacks will attest to.

• This was perhaps the best day for Detroit's kicking competitors thus far. Combined, Nate Freese and Tavecchio went 11-for-11, including Tavecchio's 41-yarder to end practice in a two-minute situation. Both also made field goals from 53 yards during a special teams section of practice. Meanwhile, Sam Martin is having a great camp punting. He continually boots punts of more than 65 yards and appears stronger than his rookie season already.

• Among the defenders who stood out was rangy cornerback Mohammed Seisay. The Nebraska product, whom I wrote about more in depth here, is still a longshot to make the roster. However, with uncertainty in the final one or two cornerback spots, a strong camp could make him a consideration. He read a pass to tight end Eric Ebron perfectly during one-on-ones and broke the play up well. He wasn't the only defensive back to grab attention, as Darius Slay continued to have a strong camp, including a good pass breakup in the one-on-one session.

• Mentioned Kevin Ogletree on Thursday and he put together another good practice, but Corey Fuller is starting to catch some notice as well among wide receivers. He caught a long pass in the two-minute drill from Dan Orlovsky after easily beating Greenwood. He also had nice catches during the receiver-vs.-defensive back session on both Nevin Lawson and Cassius Vaughn. He is a much more confident player than he was a season ago and looks like a completely different one -– an assessment he said he agreed with following practice.

• The Lions return to practice at 10:30 a.m. Saturday for their final day of the first week before taking Sunday off. Like Friday, Saturday is expected to be a fully-padded practice.
