Let me introduce you to the Rams designated clipboard holder: third-round 2015 NFL Draft pick Sean Mannion.
Sean Mannion was a good prospect coming out of high school. A four-star recruit out of California, he was offered scholarships by a bunch of west coast schools before picking Oregon State. He actually grew an inch while in college (now 6’6"), and bulked-up a bit (229 lbs.) and also grew as a QB.
He has decent arm strength and accuracy (more on that below), started for four seasons at OSU, and finished his career with multiple school and Pac-12 records.
