This news may have been expected for some time now, but nevertheless it has finally come to fruition and it is certainly a welcomed development. Per ESPN:
"We just met with Coach [Nick] Saban and he's committed," Cris Carter said. "It's a combination of the coaching and the structure and for Duron's maturity. All of those things make it a good match."
For now all of the news articles say that Carter merely committed to Alabama, but I imagine that he probably went ahead and signed his letter of intent this weekend, even though news services are using the "commitment" parlance. Obviously, though, nothing is official until the LOI is signed and delivered -- cough*Cyrus Kouandjio*cough -- so for now we'll keep the headline as committed and will update accordingly when there is confirmation that he actually signed.
In any event, this is a big addition for the Tide, and one that should reasonably be expected to pay major dividends this fall. Much like Aaron Douglas, we know for a fact that Carter can play at this level, and we are in great need of a physical presence outside with the departure of Julio Jones. Moreover, just apply some common sense here... heavily talented, deep teams do not sign JUCO transfers in April so they can be the #4 player at their position, that's just not how smart coaches allocate scarce scholarships. Obviously he needs to stay healthy and pick up the scheme quickly, but I think you can safely assume that Carter will be a major contributor come September.
