College football coverage over here in England is pretty much zero. But they're bringing in some serious experience, Tarver use to coach at the 49'ers before moving to Stamford.
Looking over the numbers, his record there was pretty impressive last year. But I don't hold on Collegiate statistics transferring to NFL alone. The defence needs the experience he can bring though, and if he can administer a strong sense of discipline and bring the godawful penalty record down with it, then I'm more than happy.
I'm more intrigued about Hoffman as special teams co-ordinator. I just assumed they let Janikowski and Lechler run whatever they want, worked pretty well last year. Janikowski setting franchise records, tying the national kicking record, while Lechler was having some of the best punts of his career. Not to mention the number of fake plays they got off perfectly, and one they would have had... had they not had a penalty on the play.
I'm still adamant that Oakland for all it's flaws has the single best special teams unit in the NFL, not sure what Hoffman will bring to the table there.
