Actually, a pretty thoughtful post. I agree with most of this. I take exception to the last sentence - a long career does not necessarily translate into a better career.
Again, if you want to talk about best college career by his criteria, it would be hard pressed to have a better college career than JBo, a guy who racked up crazy career stats in a 6 year career. He also only had one 3rd team all-conference season in the six and never made it out of the 1st weekend of the tourney. I mean is that a better career than a guy who makes a 1st team all conference team and heads to the NBA after year 2? I don't think so, but that's just me.
