Passionate sports fans love their teams and often do crazy things in support of them, but the situation involving Purdue head coach Jeff Brohm is really something else.

Brohm, a Louisville native and University of Louisville alumni, was widely considered to be a candidate for the school’s open head coaching job after Bobby Petrino was fired earlier in November. Brohm’s strong ties to the area and to the program — in addition to being a player, he was an assistant coach for Louisville for six seasons — made it seem likely that he’d return home to lead his alma mater. It was even erroneously reported that Brohm would make the jump.

As Deadspin explains, that was not what happened.

After meeting with Louisville AD Vince Tyra this week, Purdue reportedly offered Brohm a sweeter deal to remain in West Lafayette. Brohm decided to stay put. That decision did not sit well with some “passionate” Louisville fan.

Trinity High School, where Brohm was a student and football player in the 1980s, received a threat, which was directly tied to Brohm’s choice to stay at Purdue. Per the school’s website: “Trinity officials were notified by police of a threat against the school due to Jeff Brohm deciding to remain at Purdue.” Classes were canceled Thursday as a result.

Passion is defined as “strong and barely controllable emotion.” Perhaps some fans need to rein it in a bit.
