Without reading the 2nd & 3rd pages I'll respond to these for now.
Most of that discussion will be based on this years performance.
Yep.
I wouldn't waste a 2nd on a running back.
If he leaves then I would.
Tough to say. Pace likes to reward his own guys and prove to the locker room that they do that. He touches the ball more than anyone beyond the Center and Mitch. Dude's a beast & if his catching improves he'll be top 3 overall. That'll make his value explode. It'll be up to Howard on whether he gives the hometown discount or not, but I doubt he gets PAID BIG TIME with the rest of the roster needing 1-ups around then too.
Likely he'll be offered a reasonable but lower extension early, then either take it or be allowed to test the market, possibly get tagged for a year, then go FA & either sign or go to highest bidder. That's what I'd do with him. Up to him either way, which is reasonable.
I will say that it's possible he is traded for a decent pick IF it looks like he'd prefer to hit FA market. Can't see them letting him go for nothing. Interesting how it plays out but this is entirely based on expected continued dominance. Anything less, he gone or signed on the cheap, shorter-term prove it deal.
