This really comes down to recruiting.
KD recruited role players.
Get a big man, regardless of actual ability (Zeke, Hughes). Not that Zeke was not a great player, but he was a rim defender. Not too much offense, considering he was 7 feet tall. Tree was the inside offense in those days.
Big wings who were three point shooters (Reggie and Jake). But not much inside play. Role players.
Groce seems more likely to recruit ATHLETES. That makes a big difference in a tournament.
When George Young was the GM of the NY Giants, his philosophy was always to draft the best athlete available. LAWRENCE TAYLOR was the best athlete available. The rest is history.
IF Groce can bring in some good athletes, the rest will take care of itself.
