It looks like Rumph has a very good recruiting pedigree, with experience in Memphis and in South Carolina. And with some of the players he's coached, he's got something to sell to recruits.
On the other hand -- and you don't know how much of this is sour grapes, etc. -- I gather that some Clemson people think he's a great recruiter but not a great coach. South Carolina people seem to agree, but also, they might be getting a little more worried about Clowney.
In any case, if Saban jumped on him so fast, you gotta figure he feels like he got the guy he wanted.
