He can't create this kind of roster? He did in 2012 like you said but I'm assuming you mean with all of his players that he recruited. If that's what you meant then I can understand that. I would argue that he did technically create that roster as well cause he brought in the most important pieces although Darius was a HUGE part of that championship.
I'd also argue that Calipari has made repeated attempts at creating this type of roster again since 2012, only to have it fall apart because of transfers or players playing beyond expectations and leaving for the draft. I think he's been a victim of his own success to an extent. He's the best in the business at developing quickly and he gets the best players in the country. So, in turn, these "lower" ranked kids that are recruited for stability within the program practice against the best everyday and several of them have played beyond what was expected then entered the draft. That's just the nature of the business now and it's become "The Kentucky Effect".
So, we haven't had much luck in recreating the type of roster we saw in 2012 but I don't think it's from lack of trying. Cal has always went after a couple "lower" ranked guys for stability but it just hasn't worked out yet. The whole mentality that you have to be a pro to come here has just gotten out of hand. I'm sure some of it is Cal's fault but I think the majority of it is a product of our success and particularly our success with young players. Cal's not perfect but contrary to what a lot people on here believe, I definitely think he has made an effort to stabilize the roster with some multi-year players. It's just backfired on him so far. I see him building a similar type roster in 2018 with the base of that team coming from the guys we got this year. If we get Bamba, I think we have 2 OADs in Vanderbilt and Bamba but that's it. I would love us to only sign 3 players in 2018. That would mean that we are getting a lot of players returning to our team form this year.
Lastly, I do agree with you that it's going to take a mixture of upper and under classman to win a title. Until it's done won with all freshman, I'm always going to believe that philosophy. With that said, I think Cal is definitely capable of recreating that type of roster. My personal opinion is that he's going to go after a few more of these 30-100 type players that will be here multiple years to add in with the elite OAD prospects. I think he knows he's getting towards of his career and he wants to be in the conversations with Williams, Coach K, and Rupp that have multiple titles to their name. The 30 for 30 showed me that he does really care about that sort of stuff. I hope I'm right cause there really hasn't been much that he hasn't done that he's wanted to do.
