We used to get buckets all the time without the ball ever touching the floor in the 90's, Auggie clearly just discovered Uconn basketball in 2004 or so.
And yet UCONN won 3/4 of it's NCs in the 2000s. I'm not politicking for the offensive scheme mind you.
But overall you are right, he is running Calhoun’s offense that has been abandoned by nearly every other coach at every level because it’s not efficient or effective. Hey Barry Switzer won several championships with the wishbone. It won’t work today. Neither does Calhoun’s offense. I bitched about his crappy offense even when he was still the coach.
The offense itself isn't necessarily a problem. It may not be the most efficient, but it worked for the guys he recruited. JC recruited a lot of long athletes. These guys were a force on defense, but were limited somewhat offensively. Most of his old teams probably wouldn't have thrived in a modern offense. Note, 2004 could do anything.
End of the day, the best players usually win it (which fits Jordan analogy). UCONN had the best (and often toughest) player in the country in all it's titles (Shabazz, Kemba, Okafor, Rip). You can argue against Rip, but I'd take him over Langdon any day of the week.
And yes, KO's recruits neither are suited to the JC defense and offense, nor do they contain the best players (not even close).
I've no problem changing offenses, but I don't believe the JC system is dead. People were saying it for years, but it still delivered Championships. It's hard to claim it wouldn't work anymore when 4 and 7 years ago it won UCONN titles.
Recruiting and, more importantly developing players is THE most important thing imo. It's amazing how much better offensive/defensive schemes work when you have a great collection of guys and one or two ELITE players.
