Russel Wilson is sort of rewriting what a small quarterback can do isn't he, fair enough he's not an option guy. Washington is running the pistol, not just running out of the pistol formation but actually using some elements of the pistol in its playcalling, not to mention its the second year in a row that Oregon's kelley has flirted heavily with NFL jobs, so it seems teams are at least interested in bringing in systems that aren't what we think of as Pro style offenses.
Granted to you both that Kelly's system he used at Cincy probably wont' be making to the NFL and option is also probably a no go, but what he ran at ND this year, mostly out of necessity and lack of a top qb, could work in the NFL. At least as a GM could probably believe some version of Kelly's system could work.
I'll concede my stance just to end the argument
