Yep. He needs to be recruiting a knockdown shooting guard and a true stretch 4.
I think there's going to be massive growing pains trying to play Dillingham and Wagner together. Two ball dominant guards whose entire career has been built on having the ball in their hands. Combine that with the assumption that Cal will favor DJ as his lead guard and there's potential for some backcourt drama.
He needs options at the guard spot and he needs actual wings and forwards. Not guards playing wings and not centers playing forwards. I'll be honest, as a non-UK fan I hope he starts Oscar, Bradshaw, Edwards, Dillingham and Wagner. What he should be doing is recruiting guys like BJ Mack or Oliver Nkamhoua. A lineup up Bradshaw, Nkamhoua, Edwards, Reeves and Wagner would be far more dangerous IMO.
