Kalani was clear that they had been holding receivers all night, and frankly, that is Utah's MO and part of what makes their defense great. Not only would they rather hold or commit pass interference then give up a big play, they regularly do so, because they know that it won't be called that often (like holding by the O-line, they know that refs miss most penalties). I compare it to speeding--you may frequently drive 80 in a 70, and most of the time you won't be pulled over. But every so often, when you're pulled over for going 10 over the speed limit, you just have to take your medicine and pay the fine because in the end it was a violation. If you going to reap the benefits of extremely agressive play, then you need to be prepared to suffer the consequences.
