Not really sold on the guy that replaced Galliford as editor at Rumblings, but he put together a good primer imho, beefy read. Don't necessarily agree with all his conclusions but I think he put together a decent overview.
He covers 3rd CB, RT, 3rd safety, FB, 3rd WR, and has a reasonable take on Reggie Bush.
