Don't know about taking two each. Two corners, sure, a mid-late round flyer is always a good idea. 2 OTs, I would be hesistant. With Davenport, Rankins, Henderson and even Lamm on the team, the position is crowded and two of the guys are still developing. Both Rankins and Davenport showed enough to me to give them some more time and see what they turn into. I would much rather take 1 OT with our first pick (even trade up if you have to) and one interior lineman.
We still have questionmarks at HB and WR, maybe also TE and DE, backup QB and maybe more depth at ILB/OLB.
