Barring injury I think it actually helped both on NBA path...but I have to tip the hat for Fran's masterful slow roll of his twin legacy recruits.
First off, full credit that he signed them when a lot of programs overlooked them. A lot of posters on this board made pretty stupid comments jumping the gun when they signed.
Second, it was VERY obvious that they both had the talent to start or effectively play starter minutes immediately as freshmen. If nothing else they were natural rebounders immediately who grab rebounds seemingly effortlessly. I'm not at all shocked Kris is rebounding at elite level the first time he's been given starter minutes.
Last year it was clear Kris was easily their second best player and should have been getting heavy minutes, not playing behind Fran's kids and other less skilled players. Kris's advanced metrics per minute last year were among the best in all of college basketball...I'm talking compared to All Americans in many ways he produced right with them per 40 minutes.
Fran is going to end up getting 5 seasons total out of them when if he had played them heavy minutes right away he's looking likely 1 for Keegan and 2 for Kris...maybe 2 for both, no way he has Kris as a Junior if he played them both a lot. As long as neither get hurt (one already didn't) I think it works improving their stock as first rounders drafted to play for a team vs a "project" player taken later.
Keegan is not lighting the world on fire thus far very early, but he's an NBA player and belongs. He did utterly dominate the summer league and I think can still really improve into a key player for a team. He's drastically better than Wisconsin's Johnny Davis which I was telling everybody was obvious last year (could be a bust already).
The brilliant thing is there's apparently blood loyalty with the twins (or they are just patient as ****), so it's not like Kris was going to say "screw this" and transfer after he got less minutes than Fran's kid last year even though he's 10x the player. Connor is a career 11.4 PER player and Kris is a career 26.3 PER and they both played 17 minutes a game, Patrick played 25 minutes a game. Some might think that makes Fran a bad coach...but if he had always played Kris and Keegan heavy minutes he has no Kris at all this year.
