LTs are nearly as valuable as QBs. Yes, we have Gross, who is 32. Make sure you value the position. Otah will be gone next year even if he stays healthy, or he could kick inside. DT is deep, and after Reiff, there is a dropoff.
You could argue that we need to know what players are about in the event we want to trade. Never trade unless you know how badly the other side wants what you have to offer.
This. Gross might have 3-4 more years left in the tank, and those will probably be best spent at RT. We made a huge investment in Cam last year and we really need to make sure he is protected.
