Here's a video someone uploaded from the end of the Longhorns game re: five second violation.
↵
When counting it on my handy stopwatch a couple times, I get 5.2 to 5.4 seconds every time. Close, but above five seconds, and definitely still in the neighborhood if I have a slow thumb. I think the referees in college basketball make a whole lot of mistakes worth criticism, but one of them is not calling the five second violation. In this case, it was called correctly, and while unfortunate, the problem is with Joseph, not the ref.
The uploader also says he only counts to four, which is blatantly incorrect if you actually watch it, so that idea isn't going to fly.
↵That said, the fact that this is up to debate, a man counting, and people timing YouTube videos on their stopwatches is a problem. Even if the call is correct, striving to eliminate controversy would be a good idea, and having five second calls on an objective timer wouldn't be hard at all. Oh, and maybe replay for the ends of games. I don't think the mistake here is the call, the mistake is the fact that there's room for people to argue about a huge call, and there's also a problem with calls like this not being consistent.
↵This goes for you other sports, too.
↵UPDATE: With a few more timings, I get just under five seconds a couple times by the time Joseph calls the time out. I'm less sure this is a five second violation, but not sure the call is worth as much criticism as the fact that it's up for question. The refs didn't screw the Longhorns, but the NCAA is screwing its fans when it gets to this point.
