This is just speculation, but Incognito has experience at center. Down the road, if Grove continues to have health issues at center and provided Incognito can keep his head out of his butt and not be a butthead and head butt other players...
Might Richie Incognito be developed into a pro-bowl caliber center? He has great size 6-3 324 to handle some of the mammoth NT especially in the AFC East and has a very nasty attitude.
Imagine a line of the future with
Long (6-7 320) Jerry (6-5 328) Incognito (6-3 324) Thomas (6-4 310) Carey (6-5 340)
