Trent Dilfer threw an absolute temper tantrum on the UAB sideline after a defensive penalty

Trent Dilfer threw a huge hissy fit on the UAB sideline over a sideline.

New University of Alabama at Birmingham football coach Trent Dilfer might want to cool off after throwing an absolute temper tantrum on the Blazers sideline during a Saturday game against Tulane.

After the UAB defense got caught for an illegal substitution for having 12 men on the field, Dilfer lost his top and began screaming at a handful of his assistant coaches over the snafu.

We get being frustrated by self-inflicted penalty like this, but the former NFL quarterback throwing a legitimate hissy fit on the sideline over something like this is just childish.

It recalls the time, while coaching in high school at Lipscomb Academy in Nashville, Dilfer went viral for shoving one of his players in a loud dispute.

Dilfer behaving like a toddler is a bad look for the first-year UAB coach as he’s going to have to learn how to handle situations like this on a college sideline.

The 1-3 Blazers have a lot of work to do this season, and it looks like keeping his cool will be on Dilfer’s self-improvement plan as a head coach.
