I don't know why we can't recruit a QB. It's been a mystery since Ell. But I'm sure it has nothing to do with blood loss.
Sams has the best video of any recruit I've seen Snyder recruit since Zac Robinson. My reaction to seeing their Junior highlights was basically the same (i.e. Pretty meh). My reaction to seeing their Senior highlights was exactly the same (i.e. Jaw dropped).
You may as well consider Sams a 4* dual-threat QB. Had his high school team not had an FCS QB in his class that he had to split time with, they would have played him full-time, and he would have simply blown up.
I mean, I remember them all. James Battle, Robert Johnson (JUCO), Robert Johnson (Prep), Robbie Ried, Omar Jacobs, Bernard Jackson, Nick Patton, that screw up lefty kid that asked Snyder for money, Josh Portis...and the only one that ever had video that looked like Sams' was Robinson. And when you look at the list above, probably all four-stars if you dug through Rivals, none of hem had the career that Robinson had by a mile.
Snyder got his QB last year. The fact that he's getting tutelage from a guy with Klein's attitude is just icing on the cake.
