While I hope that's the case, I see it being a 2 year thing, and that's why I refer to it like a rebuild. 2 years is too long. Hell, even 1 year is too long, according to Rex.
I don't see us finding heady starters at S and LB, and another starting DT/DE to replace Kyle, and a starting DE/OLB to replace Mario, and another S for depth, and a starting quality WR to replace Percy, and a starting OT to replace Cordy, and even a quality OG to possibly replace Richie. Lots of holes to fill in one year.
