Saying that they only go after the best and more polished off recievers. . .
I did not say that, or that they "only" go for anyone. What I said is that Alabama wants big, fast, physical, coachable WRs who fit in their program. Because that is what they want, that is what an Alabama offer tells me about a player (unless you are some freak 5-star like Julio who could have put up much, much bigger numbers at another school, IMHO). It does not tell me the kid is going to be a Top 100 player, although he could be!
You may be right that they look for polished kids, but they are certianly not looking for WRs who can take over games as Freshman, unless they are trying to keep another school from getting him. Saban simply doesn't play that way.
A non-5 star WR getting an Alabama offer is different than a WR getting a Oklahoma, USC, FSU, LSU, offer. They play differnt styles so the offers don't always overlap. If you get both, you may have multiple skills sets.
I think we want Justin to over-power CBs on the boundaries and in the endzone in single coverage and to set the edge. Its part of replacing Floyd. I personally think he's going to be a stud.
