Kentucky won the National Championship with a 6-man rotation featuring:
7th man Witjer was also a freshman, but only played 11.6 mpg, 3 in the NC game.
Predictably the national media and a lot of message board posters have gone overboard, obsessing over the 1 and done phenomenon. Take a look at the other three teams that made the final four and it appears that this year's Kentucky team was something of a fluke.
Kansas's 6-man rotation included:
7th man Young was a junior who played 11.4 mpg.
Louisville's 6 man rotation included:
1 Freshman (26.0 mpg, 4th leading scorer on team)
They had 3 guys who played 12.5-13.5 mpg, all were juniors.
Ohio State had 5 starters playing 25.4-33.8 mpg:
They had 4 backups playing 10.2-11.4 mpg:
So... for the other 3 teams in the final four, only 1 freshman got meaningful minutes. All 4 teams had at least 1 senior playing an important role.
On the flip side you have 5-star problem children like Jabari Brown and Josiah Turner who end up doing more harm than good. Even a "success" like Tony Wroten, who scores a lot of points, may end up hurting team chemistry with turnovers and a me-first attitude while blocking the development of another player who will be able to help the team for 2 or 3 more years.
Let Arizona, Washington and UCLA fight over the 5-stars. That will leave more quality 3 and 4 star guys for us to recruit. Ideally we'd have a dependable group of 6 or 7 upperclassmen playing smart basketball and winning games with another group of 6 underclassmen learning to play Montyball and filling in off the bench.
