This is why we hire guys like Hurley and pay them handsomely to make the tough calls.
I think Calhoun took Ollie because he committed first rather than wait on his then rumored top choice (Travis Best?). Based on how organized he is, it would seem Hurley has identified his top 2 or 3 choices at the 3, 4 and 5 and will pressure those visiting to get a commitment now rather than play the waiting game.
For example, if Cockburn is thinking he's a one or two year player is he that much better than Mitchell or Wahab who may well be four year players and help solidify the lineup during these growth years? Or do you bet the ranch that Cockburn is worth waiting for?
