It seems/sounds like the Big 12 Tournament is a reasonable target. There won't be a need to rush him back for WVU at home and TCU on the road the last week of season. (although every game is losable)
The big 12 tourney won't start for 2 and a half weeks.
The concern with Big 12 tourney would be the back to back games. Kruger has shown to be very good rotating guys in and out, so I don't think that's too big of concern. 10-12 minutes of Buddy is better than 0.
