Positives: Might be the toughest back in the league. Has played well with broken ribs and broken leg. Takes more than one guy to bring him down. Solid inside runner.
Negatives: Don't run him outside, he's not quick enough to turn the corner, and hesitates picking his holes, he would rather make a hole. Fumbles way to often to not be waiting for it every time he touches the ball. His hands are very small, so don't ask him to catch screen passes. If you call a screen pass to him, he's likely to run the wrong route. If McNabb trusts him to pick up a blitz, he'll get killed.
Overall: Henry definitely is among the top 15 backs in the league because of his bruising downhill running style. When he finds a hole, I love watching him run because it looks like he just glides even though he isn't the fastest guy.
McGahee ended up in Buffalo because Donohoe was looking for the best player available, not because of anything Henry did. It just so happened that the McGahee thing worked out better than anyone thought, because can do everything Travis can't, and dominate doing it.
