I'd take Spence and Butler. Unless Baalke beefs up his DL signficantly, Spence won't be nearly as effective. Thus, I like Butler in the 2nd. TB will have a chance to sign a couple of DL studs in FA, as well. It's not just about the front 3 starters, it's assembling quality depth, as well. Everything's better when you have studs up front.
