maybe more than that, but I expect Tre to be a factor and Allen has already shown his ability even with a small resume. Zach is a guy I have liked (gut feeling) but absolutely no proof good, or bad. The 1 game I remember with Tre was his INT returned for a TD only to be negated because of his penalty, that doesn't take away his ball tracking and return ability.
Zach was very timid in his running, but IMO he was a very green cat, that said I liked his movement, looks like if he "gets it" he can be a very fast guy, explosive.
