Scouts show up to workouts and can immediately fall in love with a quarterback's skill set, if he has a cannon arm, incredible release and tremendous physical tools.
The guy in this year's NFL Draft who fits that criteria is Kentucky's Will Levis, who transferred from Penn State. There are still huge question marks about whether Levis can actually play quarterback in the NFL, but that hasn't stopped pretty much everybody from mocking him to be a top 10 pick.
One quarterback in the draft who could be described as kind of an anti-Will Levis had a visit with the Steelers on Wednesday, the first QB the team has had in for a top 30 visit.
