There's been comments about him not being fast enough for the NFL, that he can't do what he did in college and also that he won't be breaking tackles like he does in college. I just summed it up.
Saying he won't be breaking tackles like he did in college is not the same thing as saying he isn't strong. I mean, it's the NFL. Nobody breaks tackles like they did in college and the vast majority of Jeanty's games were against Mountain West opponents that don't have close to the level of talent that even bad NFL defenses have.
