Summary: Hiller projects as a career backup because he simply lacks the arm strength to drive the ball down the field. Some team will take a chance on him and try to develop him into a starter, but defenses can simply shut him down by challenging his ability to drive the ball down the field. Hiller has a lot of tools a quarterbacks coach can work with, and he might end up being a valuable project, a la Matt Cassell. Hiller's decision-making will probably get worse in the NFL as he will face much tougher defenses with his limited arm.
Player Comparison: Sage Rosenfels. Hiller and Rosenfels lack the arm strength and project as backups.
I'm sure it's because your "NFL Matches" section is just the usual copy/pasta from other scouting report articles, but I literally spit out my drink reading you suggest Mixon as a fit for the Ravens. Zero chance that happens lol.
