I generally agree with you about not taking safeties early, but would consider a top 10 pick on a safety if it was a superstar type. Kenny Easley. Sean Taylor. Eric Berry. Earl Thomas went outside the top 10, but given a do over and with hindsight, I'm pretty sure many teams would take him in a heartbeat, he is a legit DPOY candidate and the best player on the best defense in the league (he might be the best player on the team, period). You can make a case that the safety position is even more important than it was a decade ago, with the proliferation of TEs like Graham and Gronk.
But Clinton-Dix and Pryor aren't in that class, and may not even be top half of the first round grade like Vaccaro and Reid last year. Not sure there is an obvious top 10 CB, either.
If we can trade down once or twice, I like the fact that we can have the best of both worlds, still get two potentially blue chip, elite players at need, high impact positions (LT and WR?). Maybe even three if we acquire CLEs two first rounders (FS or CB?) and also possibly multiple second and third round picks for positions like interior OL, LB, RB, more DB.
I don't think they take a LB in the first (rationale given in the other thread), and do think they take a QB, possibly somebody like Murray round 4-5.
