Maybe the plan is to trade for him AND still keep JJ? Move him to LG... then the Bills would have a monster OLINE with JJ, Shelton, Teague, CV and MW.
That would work for me.
If his numbers are really that good (cap wise I mean), and if Denny Green would do it, then the Bills may be able to afford both Shelton and Jennings.
Is it possible?
