I'm not saying they won't pan out, but the reaction froma lot of tsun fans is that Hoke is "cleaning up" when, in reality, he's just taking table scraps. One of them might turn into players, but he's not out there snagging blue chip guys that would otherwise be looking at elite programs. He's pretty much getting the same quality kids rr was. Those kids would go to scUM regardless of the coach. That may very well change, and he's done okay given the contraints he's working with, but he's not proving his recruiting accumen yet. Harbaugh would have brought in some elite kids immediately, IMO. Hoke may very well have if he was hired after THE GAME instead of the ridiculous plan they followed.
As for the DC, he might turn out to be a real good one, but he still needs players. Also, it means another scheme change...the 3rd in 4 years now, I think. He has his work cut out for him. Fortunately, scUM has a pretty easy schedule next year...so that will definately help.
