Not to mention, if a guy like Durbin does in fact cut off some balls that a less quick 3B might not, odds of him having to make a strong throw after cutting them off is a must, and I just don't think Durbin has that arm.
If his range gets to a ball, he still has to make a strong throw, and probably even stronger if his range allows him to get to a ball that others can't, if that makes any sense...
