Yeah -- because his body type has fluctuated between being big enough to anchor inside and being nimble enough to counter pass rush at LT. Big focus of the offseason needs to be identifying a "permanent" position for Servais, and keeping him there. If he is going to play center, then he is a better shotgun snapper than Veterelo, but needs to bulk up. Agreed. If he stays at RT, then his body type needs to stay more lean so he is lighter on his feet.
Edit-- OL interior could be a strength, if Bleich and Dakota come back healthy. Tisdale also in the mix there, along with Vet. If Servais plays C, then there's your interior 3.
If he shifts out to OT, then I'd be fine with them looking for a C via transfer if for no other reason than to challenge Vet, the incumbent starter.
