I am glad its available. But it would be more efficient if ncaa and leagues would get together and make some modifications such as coaches challenges similar to nfl system.
I think that the college guys are ahead of the pros. Put the guy in the booth with access to every view there is. When done correctly, it could be very accurate, and very fast.
It should be completey done byt he guys in the booth. Having the ref run over and look into the peep show is way too time inefficient. They aren't gonna see anything that the guys in the booth don't see.
