Watch list: Jaguars Open Preseason Against Falcons

Saturday, the Jaguars open the preseason against the Falcons. I believe that this year, even more than in the past, performance during the games will determine who starts and who makes the roster. Here are some guys to watch on Saturday. Quentin Groves - The rookie defensive end has shown a good burst in practice and several of the offensive linemen and fellow defensive linemen have given him good reviews. I want to see how he does when he can go "live" against the Falcons. James Wyche - With Derrick Harvey out, Wyche is the guy who has taken advantage of the opportunity. Maybe he's just a developmental guy, but maybe he's more than that. He can vault himself into the conversation this preseason. You can argue that he has the most to gain of any player in camp right now. Brian Williams - His switch to safety will be a topic all preseason. I'm not convinced that he has totally bought into it. I think he still thinks of himself as a cornerback. Maybe that's a good thing, but I'm going to see what kind of a difference his coverage skills make and if he can hold up physically as a strong safety. Matt Jones - He's looked better in camp (at time), than at any other time in his career. Did his off-season legal trouble serve as a wakeup call? I'm not convinced yet. Jones is scheduled to be arraigned August 11, so dealing with distractions is going to be a hurdle for him as well. Mike Walker - Quite simply, he's the most talented receiver the Jaguars have on the field right now. How will his knee hold up? Can he be the guy the Jags have been looking for since Jimmy Smith's retirement? Stay tuned. Cleo Lemon and Todd Bouman - I think its possible that the Jaguars will only keep two quarterbacks. One will, of course, be David Garrard. Lemon has been sporadic in camp. Bouman would have to do something special to unseat Lemon, but it is possible. If the Jaguars decide to go with three quarterbacks, you have to wonder where the other cuts will be made. Khalif Barnes and Richard Collier - Right now, Barnes has the edge. Collier didn't get down to the 330-335 pound range. Endurance could be an issue. Barnes says that he's always internally motivated. Maybe so. But I think he's been spurred on by Collier being declared a contender for the starting spot at left tackle. Drew Miller - The rookie from Florida looks like a practice squad candidate, but his technique is good and with Brad Meester likely out until October, Miller could wedge his way onto the roster as a backup.
