Tomlin unsure of what is to be learned

Steelers coach Mike Tomlin accepted his team’s role in the now-infamous fight last Thursday night that ended with Cleveland defensive end Myles Garrett hitting Steelers quarterback Mason Rudolph in the head with Rudolph’s own helmet.

Just don’t expect Tomlin to use the video of a brawl he called “ugly for the game of football” as a teachable moment. He doesn’t think one is required.

“I don’t know that we did anything to make it happen in the first place,” Tomlin said Tuesday. “That’s why I said we didn’t have anything to learn from it.”

Garrett and Rudolph became tangled up after Garrett took Rudolph to the ground shortly after the quarterback let go of a pass in the final seconds of Cleveland’s 21-7 win.

In the chaos that ensued, Rudolph grabbed the back of Garrett’s helmet and pulled. Garrett responded by snatching Rudolph’s facemask and ripping Rudolph’s helmet off. Steelers guard David DeCastro attempted to intervene, pushing Garrett away. Rudolph gave chase and Garrett swung Rudolph’s helmet, connecting with Rudolph’s head in the process.
