If in the second round, possibly. I doubt Henry drops to the third round because of his Heisman pedigree. But I've heard (and seen) as many negative comments about him as positive.
I don't think he fits every team's system, and his success will be directly tied to which team has the system most suitable for his running style. But I think the Cowboys are one of those teams who can maximize his talents the most.
Just not in the first round.
