I agree, but maybe with a few more of Richards' min, SKJ could've been a valuable 4 year guy. I'd argue NR didn't show me anything more than SKJ yet Cal stuck with him like glue. SKJ actually showed improvement while NR literally regressed.
Richards is a 7 foot big man with lots of potential. I can see why Cal went in that direction. if Richards could have turned a corner we would have been in the final four.
