I’m disagreeing with you a bit Rich. From what I can tell, both Lum and BB were very accurate passers but both lacked NFL arm strength. Keep in mind arm strength is not really how far you can throw the ball but how quickly the ball gets to the receiver esp on the out pass. Scouts actually really liked Colvin for that reason.
From my perspective Brad did not look 6-2 when we met. I actually expected someone taller but what do I know. I do think however that he will have a wonderful career ahead of him here. We just need to keep our expectation in check.
