That's an unfortunate list, for sure. On the flip side, we're talking about a program that has 0 conference titles, 2 conference tournament titles, just 3 seasons that were good enough to get better than an 8/9 seed, and just 2 second-weekend runs in the NCAA Tournament... in the last 27 seasons.
So... one could make the argument that there may be dots to connect between the fact that Missouri has not had much luck recruiting the the Top 150, and the fact that they have not really had much high level success in nearly 3 decades. Especially considering that the two really good teams that Missouri has had over that time frame both featured multiple Top 150 guys (2005 had 5 -- Carroll, Lyons, Tiller, English and Denmon... and 2012 had 4 -- Denmon, English, Dixon, Pressey along with the #1 JUCO recruit in Ratliffe).
I actually agree, to an extent, that the transfer market is changing the paradigm somewhat when it comes to recruiting. But I also agree with Gabe that the program is unlikely to ever become what most of us are hoping it can be without an uptick in the level of recruiting.
