I've paid a lot of attention to the types of team Matt Nordlander cited in his CBS Sports article about the possibility of Rutgers becoming the first team with two lottery picks to whiff on the NCAA Tournament. He mentioned how it rarely works out well when teams that don't traditionally attract blue-chippers suddenly get one or two. This idea first occurred to me back when Seton Hall struggled mightily in 2000-01 with the No. 1 class in the country joined a team coming off a Sweet Sixteen appearance (and only missed the Elite Eight by two or three points). That team had a lottery pick (Eddie Griffin) and another first-rounder in Samuel Dalembert, and yet lost in the first round of the NIT to another disappointing team, Alabama with Gerald Wallace.
The reasons that team failed were not the same thing as the issues your team is having now. In fact, they started fast before the old guard began having issues with the freshmen and factions developed and the chemistry was poisoned. Tommy Amaker was at a loss over how to handle it and I'll always wonder how it would've played out had he not bolted to Michigan.
I can see some slight similarities, though, when I look closely enough. Obviously, Steve Pikiell (who, to me, is an excellent coach) builds his program on tenacious defense and has gotten more than the expected mileage out of under-recruited and sometimes less-talented kids because he knows how to wring value out of them. From the very start (and without knowing too, too much about Harper's and Bailey's games other than that they were extremely highly rated), I wondered if they would be willing to play the kind of defense that is the Pikiell brand. To me, if you don't, the thing starts to fall apart. I also figured that part of the appeal of Rutgers to these guys was going to be their extremely high usage rates. It's hard to imagine this wasn't always part of the (promised or implied) deal to them. They are clearly both in college to showcase their talents. And I think that can be fine, expecially on a team without any real established scorers, but that still has to occur within the context of a fluid offense (and I know some feel that such a thing is not a Pikiell calling card, but I'm not sure I agree).
But the iso ball I see every time I watch these guys on offense (which is only about half of the actual opportunties, to be fair) diminishes th entiure team concept and, I think, can cause fratures on a team. All of your other portal additions came there knowing they would be the supporting cast, but that doesn't necessarily mean they thought they'd just be spectators. And I think they can reconcile their very limited role on offense if they thought the entire starting five would be giving their all on the other side of the court, but that hasn't been the case. I don't know if Harpr and Bailey (especially the latter) aren't instinctive or skilled defensive players or if they just don't care. But either way, it's a major problem. On its face, it harms the team on both ends of the court, but the locker-room implications (and I haven't heard this to be the case, to be sure) are the kind of thing that could blunt any chance of improvement.
From where I sit, this team has more than enough talent to have a winning Big Ten record and would be dangerous in a conference tournament setting. And given that your two featured guys are both freshman, it would be reasonable to expect improvement over this winter. But if this the way the die is cast, it does appear pointed toward a flop. I remember holding out hope in 2001 for that team to turn the corner, but it never happened. And it was nver going to. They made a run to the Big East semis, but ran out of gas in the second half and that was that.
