Pete Dougherty began this article talking about the battle at the number 3 cornerback position, but he ends up discussing all the positions and a lot of players.
Although both CB Patrick Dendy and WR Ruvell Martin played well in 2006, neither is presumed to be either the top 3 CB or WR. CB Will Blackmon practiced ahead of Dendy, while Martin is competing against a large cast of characters. Dendy and Martin only have one quality NFL season each and shouldn't be guaranteed anything. Both will probably have to battle for playing time with the first unit throughout training camp.
Tight end was a major zero in 2006 but none of them distinguished themselves in minicamp. It would be a really shock if any of these tight ends became a real weapon in 2007, unless TE Bubba Franks pulls another 7-9 TD season out of thin air.
OL Tony Moll played exclusively at tackle in minicamp, although he played a lot of guard in 2006. He probably had more snaps at right tackle than at right guard, but he should know both positions very well by this point. The starting 5, Moll, and 4th round pick Allen Barbre are all probably locks to make the team, but everyone else will have to play well in training camp to stick.
Although I'd been writing about undrafted free agent DE DeVon Hicks on this site recently, Dougherty didn't mention him once. It doesn't matter since no one makes the team out of minicamp, but he has to make a lot of favorable impressions to make the team and apparently he didn't make one on Dougherty.
