Every coach whiffs from time to time. Ollie's track record on this is very short, so it doesn't seem remotely unreasonable to me that it could happen here.
Yes, but this is something you only know in hindsight.
At the time Turtle was offered, we hadn't won a national championship, top recruits weren't begging to be recruited, top targets like Jalen Adams and Jessie Govan were reluctant to commit, the conference situation was a big negative, there was a risk of being shut out. Making an early offer on a once-heralded but high risk recruit with an injury is a speculative move that made sense at the time. If KO could have seen the future, he probably waits on Turtle like other top programs did.
It's OK, there are 13 roster spots and the tourney rotation is usually about 8. There is room to have a role player and time to develop a guy like Turtle. He might be a starter and a star, but even if he doesn't become that, the coaches will mold him into a useful contributor.
Not every player can be a star, and often teams overloaded with stars have poor chemistry. Turtle has a lot more potential than Jamal Coombs-McDaniel, Darius Smith, Jonathan Mandeldove, Michael Bradley, Lean Tolksdorf, Donnell Beverley, or a boatload of other players Jim Calhoun recruited. I don't think we're going to be regretting his commitment five years from now.
