I think a quality dual threat TE will do more for our offense than revamping the o-line again. Pitts is going into his second NFL season at guard and has been good run blocking. Wand had a quiet season, which is great for a first year starting left tackle, he could end up being very servicable. Wade is in his first year in our system. Other than maybe McKinney i'm not an advocate of changing much on the line unless it comes from internal competition from players already on roster or drafted.
a great TE could help us explode. Bubba Franks would really help both the run and the passing game. As would Alex Smith or Heath Miller
