That argument is not valid. The game has to be delayed for commercials. They will call a timeout "on the field" if they have to, to get in the commercials. Since they have to show the commercials anyway, why not just have a commercial every time they have to look at a (non-super critical) instant replay? The game wouldn't be slowed down any more than it already is.
The NBA looks at replays for flagrant fouls, which are judgement calls. I believe the NHL looks at replays for major penalties too. They care about getting the big calls right. The NFL should care about game altering personal fouls, if they want to appear as professional as the NBA and NHL. Cause right now, it looks like a circus.
