Everytime Troy mentions his back, I immediately remember back to a Thanksgiving game against the then Houston Oilers with a young McNair and Eddie George in the lineup.
Troy's back acted up during warmups/stretching and he could barely move without assistance. The trainers took him to the locker room, albeit slowly, and shot his back full of cortizone. If my memory serves me right, the Oilers had the ball first and Troy had not came back to the sidelines. I can't remember if the Oilers scored or punted the ball away, but Troy jogged back to the sidelines just before the offense took the field.
He looked completely stiff...completely uncomfortable...completely in pain. He could barely toss the ball to warm up, yet he took the field with the offense. He drove them all the way down the field, but his follow through was non-existant and a pass got away from him in the red zone. The pass was intercepted and nothing but green was in front of the Oiler who made the play. Troy ran the guy down and shoved him out of bounds. He landed on his back and I could tell he might not get up for a long time.
This may have been just another play, but it's one of the many reasons why Troy Aikman is and always will be my favorite player in the NFL. What an incredibly tough player who expected nothing but the best from himself and those around him.
If anyone has this footage (stargazer maybe?), I'd love to have it.
