I actually take a little different stance wrt control/eye. Because hits are harder to come by, walks seem less important to me. A walk will only advance a runner one base. A single has the possibility of a two base advance. And, if you're strong up the middle, you're increasing your chances of a double play. I certainly wouldn't build a staff with 44 control pitchers or 38 eye batters, I wouldn't be adverse to using a few of them if their other numbers matched up well. And, in all likelihood, they'll be easier to acquire because teams in neutral/hitting parks won't want them.
