Dallas Cowboys Hall of Famer Michael Irvin only cared about one thing when it came to football: winning. He cared about winning so much he wasn't afraid to throw players under the bus who didn't care about winning as much as he did.

Irvin appeared on Undeniable with Joe Buck and revealed during his rookie year he was shocked to find out that even though the Cowboys went 3-13, it didn't seem to bother some of his teammates which really frustrated him.

Irvin recalls how he would be almost crying at his locker and some of the veterans would tell him that you don't do that stuff in the pros.

“I was nearly crying in the locker room after we would lose games and a lot of guys would come by and say, ‘Come on, man, you’re in the pros now. We don’t do that in the pros. Just make sure you pick up that check on Tuesday.’ I was blown away with this, man. I was like, ‘Man, this is the NFL?’ It was the hardest year for me, to get through that year with all that losing,” Irvin said via Pro Football Talk.

After his rookie year, the Cowboys brought in Jimmie Johnson to be the coach. Irvin knew Johnson from his team with the Miami Hurricanes, and he called him and told him the guys that needed to go because they didn't actually care about winning games.

“When Jerry bought the team and we heard Jimmy was coming in, I went home and called Coach Johnson. And you know how, as brothers we have this thing, ‘I don’t snitch’? Man, I was snitching,” Irvin said. “‘Hey, man, this dude’s gotta go. He’s gotta go. He’s not about winning.’ And it took Coach about the first few months, first year, but boy, he started getting rid of everybody. And we got people in like the people we had at Miami that wanted to win.”

The Cowboys, of course, turned it around after that, and they won a lot of games when Irvin was on the Cowboys, but it's still shocking that he was willing to throw his teammates under the bus, something that isn't supposed to happen in a locker room.
