The more we learn about Vince Young, the less he seems like a guy any NFL team would want to count on as its starting quarterback.

Adam Schefter reported today on NFL Network’s NFL GameDay Morning that during last season’s AFC Wild Card game against San Diego, Young wanted to stop playing at halftime and had to be persuaded to take the field with his teammates in the second half.

Think about that. It was the biggest game of his professional career, and Young wanted to stop playing at halftime. That’s stunning for a guy who left Texas with a reputation as a big-game player.

Ultimately, Young did play the entire game, completing 16 of 29 passes for 138 yards, with no touchdowns and an interception. The Titans lost 17-6.
