Jennings stock is increasing because guys like Pace and Jones are off the market. Although there is a rumor that Pace can be had from the Rams for a 1st round pick. But this is the same thing we saw with the CB class last year, when Bailey, McAlister, and Woodson were tagged and taken off the market. And the trickle down affect made average players like Jason Webster very rich men.
Jennings is not that great of a player IMO. He's a guy that I think would make a much better guard than tackle. He can play all 5 OL positions, which is a plus, but I think his best position is probably OG. He has good strength, and moves well for his size, but I think he is not a great pass protector.
But he does seem to be turning a corner. His penalties were down this year, and he did not get flagged for a single holding penalty this year and really cut down on his false starts. So he might be ready to emerge into the upper half of LTs in the league.
I don't think he'd be a great fit for this scheme, because I don't think he's super mobile. We would be much better off if we let some other team pay him $10 million (or more) bonus to be their LT.
He would be an improvement over Shaffer, but I think he's about on par with Weiner in terms of ability.
