The fact that he slammed an opponent's face into the ice on Friday night -- for which he's been suspended a total of 13 games by the American Hockey League -- should be enough to convince you that Trevor Gillies does not belong in professional ice hockey.

But if that's not enough, remember back to two games in the 2010-11 season.

On Feb. 11, 2011, he delivered a vicious elbow to then-Penguins forward Eric Tangradi. As Tangradi grabbed his injured face after the hit, Gillies dropped the gloves and started beating the crap out of him. After Gillies was pulled off of Tangradi and sent to the locker room, he stood just off the ice in the locker room tunnel ... taunting Tangradi.

In his next game, the first back from the nine-game suspension handed out following the Tangradi incident, he throttled Cal Clutterbuck of the Wild into the boards from behind, earning himself a 10-game suspension. Gillies has played just nine games in the NHL since.

But given that, if you still believe Gillies has a place in the professional game, here are three more points:

Trevor Gillies has never played more than 8 minutes in any single NHL game. Career average NHL ice time per game is 3:14. — Travis Hughes (@TravisSBN) October 13, 2014

In his pro career, Trevor Gillies has played 57 NHL games and been suspended for 31 games. — Grave Lozombie (@DaveLozo) October 13, 2014

Another Trevor Gillies stat to follow that LRT: In 852 games over 19 years in the OHL/AHL/ECHL/NHL/Europe he has scored 18 goals. Insane. — Adam Gretz (@AGretz) October 13, 2014

Gillies is not an effective hockey player. And no matter how apologetic he might be over the incident on Friday, he's been suspended way too many times for us to believe he's ever going to change as a hockey player -- or, rather, a glorified night club bouncer with ice skates and a pair of fists.

Trevor Gillies is eligible to return to the ice for the AHL's Adirondack Flames on Nov. 15.
