Russel Wilson or Bob

[30gut]

Obviously all 3 are good QBs, good leaders, good runners.

They're all very close in arm talent to my eye:

By arm I mean the combination of quickness of release, velocity, touch (deep ball) and accuracy.
In terms of pure velocity I would put Kaepernick is 1st. In terms of pure accuracy I would put Wilson is 1st Griff is very close because he can make some perfect passes but his ball location is inconsistent (often 'wild high'). Quick release I would put Griffin 1st. Touch(deep ball) tie between Griff & Russ.

Running ability: Griff is the most dynamic, he's a threat to score on any carry. Kaep isn't far behind though. Russell isn't as fast but he's more then useful enough to make the read-option plays work. Griffin is by far the most reckless. Kaep and Russ imo have far better running instincts and awareness about when, where and how to uneccesary hits.

Progression reading in a rhythm passing offense 3-5-7 step drop passing:
Russell Wilson is head and shoulders the best imo. Griff & Kaep operate schemes that far more run-action based and often result in simple half field/hi-lo reads.
