I would say this is a decent guestimate on how the scenario will play out. I still think Light is the best option this year. Vollmer is the LT of the future. The Pats will try to trade Light in the offseason while he still has value (Calling Scott Pioli and Josh McDaniels).
McDaniels is out of the question. They've got a great young line, and frankly, Clady is better than Light.
Pioli though, the Chiefs line is a mess (as is the raiders, who are always an option)
