Some people at your place of employment will overlook concerning issues as long as that person can continue to perform and meet the expectations of the job.
Nowhere is that statement more true than in the NFL. Lions coach Dan Campbell offered a view into just how much the league ignores troublesome issues from their players, recalling a player he coached during his tenure with the Miami Dolphins who he claims "came in every day just reeking of alcohol."
According to Dave Birkett of the Detroit Free Press, Campbell pretty much indicated that it was fine because the player produced and "loved the game of football."
“I remember I had a guy in Miami, god he loved ball,” Campbell said, via Dave Birkett of the Detroit Free Press. “He was a dynamic football player, but he came in every day just reeking of alcohol. He was probably on a bender for who knows how long, but god he loved football. He showed up, he didn’t have any M.A.’s [missed assignments], he hustled non-stop, and it’s like, you know what? You’ll find a way to make that guy work. Not saying we want those guys, but he loved ball, and he had success. And he’s still playing today, by the way.”
This revelation should be no surprise considering almost every NFL team has taken a risk on players that have been deemed "troublesome." It's still unclear who Campbell is talking about, but he does admit that the player is still playing in the league today.
