Not sure that there was a bigger booster for Michael Sam than me.
That said, I value production, dedication and hard work, ESPECIALLY in the face of any discrimination, real or perceived.
If Michael Sam wanted to be a working professional football player, he would have stayed in Canada and gone the Cameron Wake route and proved to the NFL that he belonged in the NFL.
Instead, he made the journey for the next openly gay athlete attempting to make it in the NFL that much harder because now there will be questions of heart, dedication, focus, priorities, determination and resilience.
As to his point, might he have gotten slightly more benefit of the doubt if he were drafted higher and maybe made a roster? All we can say is...maybe. But also, maybe not. He has no right to make claims based on uncertainty.
I have no problem saying the NFL as an institution has an issue with gay athletes. Kerry Rhodes is a perfect example. Two outspoken advocates for gay rights were out of the league the next year.
So, while the NFL certainly has issues to address, what Michael Sam always had to do was work harder than everyone else and persevere. Being first is more than an opportunity, like it or not, it's a responsibility. Unfortunately, he squandered it and for that he has no one to blame, but himself.
