Imagine this: you're a pass-catching tight end out of Michigan. The Houston Texans think you're so swell that they spend their 2003 2nd round pick on you. You're gonna be one of the weapons in the passing offense, giving David Carr that target over the middle the offense needs.
Then in the first week of your rookie training camp, you injure your groin and miss the whole season.
Then the next year, you make it through camp, only to injure your groin again on the very last day of camp. You miss the whole season again.
Now, in your third year, you don't even make it to camp - you tear your ACL in non-contact drills in organized team activities. On the downside, you'll miss the whole season again. On the upside, your groin is OK.
If this sounds familiar, then you must be Ben Joppru, the Houston Texans tight end. Maybe next year, eh bub?
