There's been talk about Chang being the QB of the future, to being the 3rd string QB, to not even making the team. There's talk as to why Chang was not drafted in the NFL to whether or not he can throw deep. I just have a feeling a majority of us haven't had a chance to see him really play yet. So i did research.
Found some highlight clips of his football career at http://www.TimmyChang.net (looks like a fan-made website). But it's got some good clip of Chang from the NFL,NFLeurope and college running different offensive systems. You guys should see the College clip where he's playing the Run-N-Shoot. Which looks very similiar to the CFL.
Obviously, these are highlight clips so you're only seeing the good plays, but you can get an idea as to what Chang can do. If you have questions about his deep throws, watch where he throws the ball 55 yards on a strike while back-peddling. It seems he's most comfortable while in the shotgun formation. I think he'll have an easier time adjusting to the CFL style of play than most other rookie QBs. Hopefully, this will lead to more educated discussions.
