I actually don't mind when Sheed's moving around the mid-game range. A lot of his post moves result in jumpers anyway.
It's the roaming around the 3 point line that usually kills teams. That's where you don't want him. Because even in the mid-range you can over power, outmanuever or just shoot over a defender (especially on the bench). 3 point range unless wide open is generally a crap shoot with unfavourable odds.
