I'm glad to see more interest in Henry. It only makes sense, as while he's not perfect neither is any other RB out there on the market.
Actually, compared to Alexander and James, Henry is a peach. He's not been franchised, for one. A franchise tag means a big bucks contract for a RB. Henry doesn't come with that burden.
Compared to a rookie, Henry looks great as well. Rookies have never played a 16-game season, which is a big issue for rookie RBs. Rookies also don't know much about pro defenses, and that's also an issue. Henry, while not perfect, is more of a known commodity.
I'm glad Donahoe isn't a spaz and realizes there are lots of opportunities for trades, and not just the one with the Cardinals. He's smart for realizing that as situations play out, teams will become more interested.
