They have 16 men currently listed, they will probably keep 10 total. I'd say the bolded are the locks. I think the 6 guys in red are fighting for one of 4 spots. The guys in blue are just camp/PS bodies praying for a miracle.
DE's: D-Law, Fowler, Williams, Armstrong, Basham, Golston, Tafua
DT's: Gallimore, Odigy, Watkins, Hill, Bohanna, Ridgeway, Bronson, Bryant, Faoliu
Watkins is the vet and IMHO, that currently gives him the advantage over the others. He's listed as a (305#) DE, but plays the 1. He gives you solid NFL level play and can play inside or out. I think the FO is happy to have him, but is really hoping that one of these kids can push him off the roster.
I'm not a big fan of Trysten Hill, but I have heard some early praise coming out of Dallas for him so far this offseason. He did OK at the tail end of last season. Maybe he's finally making that jump, maybe that's because he knows he's on the chopping block. It's also a contract year so he may surprise some this year. If he takes that step forward, I'd be ok with resigning him, but I hope they don't over react (and over pay) as usual. He could regress just as quickly.
Bohanna is a huge 1T run stuffer and nothing more, but can he be so effective at it that they must keep him? Big Mike has always liked those type of guys so he will get the chance to prove he can do it. I want him to succeed, but I have my doubts.
Ridgeway is gritty, nasty type of player that they specifically went after this year. He's a fighter and make no mistake, he's here to push Hill and Bo, or replace them. I think he's got a great shot to make the team.
If you look at the DE's the first 4 are pretty much set.
Basham isn't great, but he is a better edge pass rusher than Golston. Golston brings some position flex to go inside in a pinch. But honestly, Watkins and Odigy could slide outside in a pinch just the same. Regardless of how I, or you feel about him you have to ask yourself, is he better inside than any of the 3T's? I haven't seen anything that says yes to that, so why would they use him there? Is he better at edge rusher than any of the De's? Same answer and IMO, even the DT's who can flex out are at least on his level. So I think, unfortunately he's on very thin ice.
