#3 Colin Kaepernick

New Orleans Saints v San Francisco 49ers

Colin Kaepernick was allegedly involved with a teammate's better half during his time with the San Francisco 49ers.

Kaepernick reportedly hooked up with then MTV star Nessa, who was dating the quarterback's teammate Aldon Smith at the time.

The two came to blows during a practice session and that was that. Nessa was soon Smith's ex and began to openly date Kaepernick.

#4 Marcus Allen

Allen at the 2022 NFL Draft - Rounds 2-3

Marcus Allen and OJ Simpson's wife, Nicole Brown, were rumored to have been together while Nicole was dating the star running back.

Allen denied cheating with his teammate’s wife, but Nicole wrote about it in her diary.

NFL agent Mike Gilbert, who represented both Simpson and Allen, all but revealed in a 2016 documentary that the affair took place. Gilbert said that shortly after Nicole ended attempts to reconcile with Simpson, the running back told her: "You ever see Marcus again and I will kill you."
