Officiating football games is not easy. On catches near the sideline, you have have to maintain possession all the way through the catch while keeping ball feet in bounds. There are so many things that an official has to look for on those. Correctly calling delay of game penalties, by comparison, should be a lay up. And yet, it's a rule that's treated more as a suggestion than an actual rule, and that needs to be fixed. There's really no excuse.
