University of Colorado linebacker Jon Major is my sleeper late round gem this year. He's not projected to be drafted. He's not even on most website's ranking lists....so it's a long shot for sure, but I love this kid. He plays Sam, Mike, and Will as well as special teams. He really seems like a great well rounded football player. Realistically he'd probably be a special teams contributor, but I can see him adding solid depth to all three linebacker spots, similar to Adam Hayward.
