Not sure where "Texas Terch" is, but Beard has been at Texas and Ole Miss since then.
Obviously a Beard hire would be very controversial, but it actually kind of makes sense. He probably is the closest current coach to Knight, and whether you think that's a good or bad thing depends on you.
Only two people know the full story of what happened between him and his fiance, and they're still together 5 years later. Whatever happened was something they were obviously able to put behind them, and I think it's a reasonable stance for everyone else to move on form it too. However, there are people that have dealt with domestic abuse in their own lives that will absolutely not accept or forgive Beard, and I'm not going to tell them they're wrong for feeling that way. Still, it's very different from someone like Bob Huggins, who has a multi-decade pattern of being a huge POS and any AD that considers him should be fired on the spot.
As for McCollum, the face that he very likely is a realistic candidate is hilarious. IU fans say "we're IU, we can get anyone" and have a list ranging from Billy Donovan and Brad Steven's to a guy in his 1st year in D1.
The most likely outcome is that the IU opening is used by Bruce Pearl, Greg McDermott, Ben McCollum, etc as a bargaining chip for a big raise and they hire someone boring like Buzz Williams or Steve Alford
