The 13-14 team had the most talent, but underachieved, mostly because Sampson, Sanchez, and Pointer were too similar to really work together. That year felt like a disappointment, despite the 20 wins, and was probably the beginning of the end for Lavin (I actually think he did a better job the following year, even though he was not brought back).
The 2010-2011 team was a senior laden group, with a chip on their shoulders. It took them awhile to adjust their games, to fit in with the new offensive and defensive schemes that Lavin and Dunlap put in. Once they did though, in about mid-to-late January, it was pretty much smooth sailing, until the DJ injury. That was the best team, IMO.
