Chargers quarterback Philip Rivers has the worst throwing motion of probably any quarterback in the NFL. But at least he doesn't have the worst throwing motion of any player on the Chargers team.
At least that is what this video from Mr. Irrelevant shows us.
Saying that Merriman "throws like a girl" is a little bit harsh. Maybe he was standing on a metal bench or something. But it is safe to say that the Chargers probably won't be calling any linebacker options in the near future. And really, passing ability isn't one of the things that you would look for in a linebacker anyway. Thankfully.
