I don't see ISU as "imploding". 17-6 while playing most of their season minus 1 starter is not imploding.
Their 6 losses:
UNI (2 or 3 point game). Good for UNI, they played great
At Oklahoma (lead with less than 1 minute to go, had a good look at the end to win it)
At Texas (lost in OT)
Baylor at home (tough loss but lead for majority of game, BU outplayed them in last four minutes)
At Texas A&M (see Baylor)
West Virginia at home (see Baylor)
Not making excuses, but their lack of depth MIGHT be in factor in losses to Baylor, A&M, and WV. It seems like good teams just have an extra gear in last 4 minutes. Would Naz Long have made a difference? Who knows. Matt Thomas has been great in his absence, but take any starter out of any lineup and you are not as strong as you were.
Big 12 title is probably out of reach, but this team still has the talent to do well in conference tourney + NCAA. Good seed + good matchups + playing well at the right time = deep run? How far? Who knows? At the same time, they could lose in 1st round. Before you make any snide Hampton or UAB comments, it could happen to Iowa (or anyone) on any given day. Beware. It sucks, but it happens to nearly everyonel at some point. Parity in college bb is pretty evident.
Finally, good for Coach Prohm for suspending McKay. None of us really know what happened. It might cost them a game(s), but no player is above the team or program. He is doing the right thing for the present + future of the program. Time will tell.
