So? The Bills will theoretically get a specific pick in the 2nd round for Henry as well. I'm not even talking about 2006, unless it's to tack on a conditional pick, a la the Dols and RW.
Using Dillon as a comparison, taking a look at their last 4 years with their original teams (i.e. 2000-2003 for Dillon and 2001-2004 for Henry which is his entire career), Dillon has 753 more yards, but 1 fewer TD. He was also 30-1/2 versus Henry who will be 26.5. And as for fumbles, Henry had just 3 last year showing he improved in that area.
Droughns plays for Denver, who always has a good running attack. As for Goings, he's the exception, not the rule. He was their 5th or 6th RB at the start of the season so even THEY didn't know what they had. People will know what they're getting in Henry.
Not even close. At worst the Bills will get a straight-up high 3rd for Henry, but I'm betting a straight-up 2nd that conditionally becomes a 1st. There is no pressure to trade him like there was with Faulk and unlike with Dillon, the market for him will be good. And no way he gets released when he's making just $1.25M next year. That's insane. At worst the Bills keep him for the year if they don't get a pick they like and let him become an UFA after the season.
