Burnett is almost assured to make the team barring injury or him doing something really stupid. I see him as like Bradie James in his second year, getting some playing time and being mainly there for special teams. If I had to gamble, I'd say he'll get time in the possible pass defense packages since Ayodele isn't really known for pass coverage.
Beriault may have some problems with his knee. I think it was Galloway who said he can't keep his knee healthy, but I don't think that was actually confirmed.
I wouldn't count on Marcus Coleman making the roster. Sure, he's a veteran and a Parcells former pick, but he hasn't been very good in coverage the last two years, is old (say what you will, but Parcells has been willing to gamble on young players over old players lately) and they only signed him to a 1 year deal.
If Beriault's knee is okay and he makes plays like he did in last preseason, I could see him easily as a backup. But, I'm really hoping Pat Watkins tears it up so they can have a true FS alongside Roy Williams.
