Most of us have resigned ourselves to at most a 24 man defensive roster. If we call Ebner our 4th safety, expecting him to be a special teams demon,
Q1) How many more defensive backs do we need?
Q2) Who would fill that position or positions?
SUMMARY OF STATUS QUO (8)
CB: McCourty, Dowling, Arrington
S. : Chung, Gregory, Wilson
CB/S: Moore backs up anywhere and everywhere
ST: Ebner
=================
The answer that I have been hearing is that we need only one player: Dennard. This solution doesn't work for me. Does it work for you?
I agree with you that Dennard goes to IR. That allows us to keep the upside and potential for the future without risk of sliding him to the PS through waivers (as long as the IR move is made during one of the cutdowns, which I expect it to be rather than immediately of course).
I agree with your 8 so far, but I would certainly include one more.
Cole/Ihedigbo/Barrett are all good candidates for that ST only backup role.
The only issue I would have with Cole is that we may be lacking someone to play the backup role to Chung--whatever you choose to refer it to, but in theory it would be more of a SS rather than a FS (understanding that we do not designate those positions). By choosing one of Ihedigbo/Barrett, we also cover that base.
9 seems like a solid number for DB's to me, but I would be in agreement with patsfan13 in keeping 25 defensive positions rather than your suggested 24. That would of course allow us to also keep 16 front seven players, while also covering the ST only positions too (when Edelman, Slater, and Demp are included in the picture on the 25 offensive positions).
EDIT: We could also keep BOTH Cole and one of Ihedigbo/Barrett too if that's the way that Belichick wants to go, in patsfan13's plan of 10 DB's. That of course would likely mean that one of the ST only LB's would be cut, adjusting the number to only 15 front seven positions. It may actually be the best of both worlds in the ability to keep 15 front seven players, while also backing up the SS designation (Chung's backup). On top of that we'd also be able to keep a guy like Cole around to add to the ST only players and backup the CB's in case of injury.
One way or another though, I would like to see 25 on both sides of the ball, b/c I think that this also includes all of the ST only guys besides the 3 specialists.
