Munchak's and Reid's big commonality

NASHVILLE, Tenn. -- Sunday's Chiefs-Titans game will feature an unusual pairing of head coaches.

While Andy Reid never reached the playing heights of Mike Munchak, both were offensive linemen. Reid played on the line at BYU. Munchak is a Pro Football Hall of Famer for his work with the Oilers.

Guys who worked as run-blockers and pass protectors aren't common in NFL head coaching ranks.

"Andy was always my favorite for that reason," Munchak said. "I got to know him through the years because of that, at the combine. I was good friends with his line coach, so we talked quite a bit over the years."

Why aren't more linemen, often among a team's most intelligent and well-spoken players, head coaches?

"I don’t know," Munchak said. "That's a good question, and I always wondered that myself. I think Art Shell, me, [Reid], that’s three of us. I think [Joe] Bugel had a short run.

"I don't know, I guess people want to do it the old fashioned way. If you're not a coordinator, they think you can't be a head coach. I guess a handful of us have proved them wrong, or hope to prove them wrong."
