Upon Further Review: Buccaneers Week 6

TAMPA, Fla. -- An examination of four hot issues from the Tampa Bay Buccaneers' 31-20 loss to the Philadelphia Eagles.

The hot seat: There's no doubt that coach Greg Schiano has entered hot-seat territory. He's lost his first five games of this season and 10 of his past 11 dating back to last season. It's probably a bit too early to expect ownership to pull the plug and go with an interim coach. But the clock is ticking and all the off-field distractions aren't helping. If there isn't dramatic improvement soon, Schiano's NFL tenure could be a short one.

The zone defense: Cornerback Darrelle Revis appeared to be looking for safety help on one touchdown pass and the Bucs seemed to be in zone on another touchdown. Revis might be the best cover corner in the league, but the Bucs aren't maximizing his skills.

The rookie might have a future: Quarterback Mike Glennon wasn't great in his second start, but he wasn't bad either. Glennon completed 26 of 43 passes for 273 yards with two touchdowns and an interception. Glennon, who isn't known for his mobility, also scrambled for a 16-yard gain. It's early, but there were some signs that Glennon can succeed in the NFL.

All for nothing? Linebacker Lavonte David is having a Pro Bowl-caliber season. On Sunday, he had a team-high nine tackles, a sack and two quarterback hits. But as long as the Bucs keep losing, David is not going to get a lot of Pro Bowl votes.
