First, so far I am a big fan of the pick and player and I think there is too much emphasis in the 1st rd. of the draft on draft age and "potential." There are plenty examples of players drafted after they have played 3+ years in college being great pros.
That said one of the factors that needs to be considered when looking at college players that stayed longer is how much of their stat advantage stems from being a mature/experienced "adult" playing against physically immature and/or inexperienced "kids."
Stockton and Nash played against other "adults" and Pritchard's stats may be a bit inflated by taking advantage of less physically developed or inexperienced "kids."
This is probably less of an issue with guards versus wings/bigs but Pritchard's stats do need to be examined with that context.
