I think the past several days have helped Travis' value as several other RBs were taken off the market. I trust TD to get maximum value for TH.
It has been written here several times already, and I agree, that even if Shelton is a slight step down from JJ, it still saves the Bills a good deal of cap space -- cap space that can be used to sign a good left guard. Take a half step back at LT to take three steps forward at LG, yeah, I'm for that.
By the way, the word is that Shelton is better at run blocking than JJ, and JJ is better at pass blocking. Well, I sure hope to see our star running back get a lot more carries than our very young QB get passes.
