I think Bullock is just a different build more than anything and I'm sure he would like to be 225, but Souf is in tremendous shape and cannot help RU offensively.........Bullock is solid and possesses a good shooting stroke.....I think Souf's rope was shortened considerably, he works hard, but is not a threat on offense at all and Bullock is just a better offensive threat.....and if Souf isn't dominate defensively, he can't really fit into a role....I think Bullock will be left SO wide open that he can probably drain a couple of threes by default.
If Bullock can defend for 2 to 3 minute spans at a time and provide at least a threat that he may shoot, he will bolt Souf to the bench and RU will be a better team attempting to overcome the Williams injury.
