I don't know if it's so much they have a bad track record as they just take so much damn time to get the players ready. That's just the nature of being a big, regardless of where they play, unless they're an elite talent. The only bigs I can think of that were whiffs were in Prohms first couple classes, Ernst and Carter. Lard was good, albeit inconsistent and a hot head. Young has panned out. Conditt has been serviceable in 2 years so far with potential to improve. And now he brings in highly touted XF. Where Steve has struggled is with transfer bigs. Jacobson was good at times, but also bad and never great. Bowie was more of a stretch 4.
Steve Prohm coached players 6'8 and over
Simeon Carter - whiff but in first recruiting class
Brady Ernst - whiff but in first recruiting class
Cam Lard - very talented but a head case
Ray Kasongo - absolute whiff. no excuse taking a kid that bad
Merrill Holden - not a big 12 player, but a bit excused due to guard talent that team had
Darrell Bowie - had highs and lows but a solid big 12 bench player
Solomon Young - solid big 12 player
Michael Jacobson - solid big 12 player
Hans Brase - whiff, had injuries and roster construction forced him to be a take, but not a big 12 player
George Conditt - has shown flashes but struggled in big 12 play this year
