Vet on the hot seat: Roy Williams

Posted by ESPN.com's Matt Mosley

Cowboys wide receiver Roy Williams will face huge expectations in '09 based on the draft picks the Cowboys gave up to acquire him last season. He was supposed to be the perfect complement to Terrell Owens, but he instead ran around looking lost in the second half of the season. His 19 catches for 198 yards in 10 games were embarrassing in Dallas.

But according to everyone at Valley Ranch, Williams has been one of the team's most committed players this offseason. During the recent rookie minicamp, receivers coach Ray Sherman couldn't stop bragging on how Williams is becoming more of a complete player. And for the Cowboys to have a chance at making the playoffs, Williams has to at least be a threat on the outside.

I can't think of anyone in the division who will face more scrutiny -- outside of the quarterbacks of course. Even former quarterback Troy Aikman has questioned the Williams trade, saying it could by "one of the biggest busts" in league history if it doesn't work out. I think Williams will be better this season, but it's hard to project where that puts him. He's had one Pro Bowl season in the league. Other than that, he's had a very pedestrian career so far.

Honorable mention: I think all eyes will be on Eagles left tackle Jason Peters. Was he worth a first-round draft pick? Well, we're about to find out. Can he return to the form of '07 or will he look like the player who was beaten for way too many sacks in '08? I think he'll be excellent in Philly, but he's still firmly on the hot seat.
