I think the team views Tyler as the starting LT, but feels pretty good about Richards as well. The plan is probably to come up with the best combination on the left side from among Tyler, Richards and Bass.
Center is the spot that worries me. I didn't even think Hoffman was worth keeping after the preseason and now he's the placeholder. He played fairly decently at center when given opportunities during the season, but I think he will get exposed if he's the starter. Of course, that's why I think we'll be drafting a center early.
