I think watching Gary Neal did it. I would like to get Lamb and use him the same way.
I think they're a decent comparison. Similar in more ways than different, for sure. Also, Lamb is not just a perimeter shooter. He has a great mid-range game, floater, and very crafty going baseline .. though the baseline thing will probably result in a good number of blocked shots in the NBA.
FWIW - Calipari has said many, many times that Lamb has the highest bbIQ on this year's team and the most diverse offensive skillset.
