My take. No one can argue ED is a pro style pocket passer deep ball assassin. So what is he as a QB? He is a tough, mobile, running, play making, risk taking leader. Not great at either short finesse touch passes or deep balls into tight coverage, but seems at least adequate at most throws. Reading and reacting quickly to complex NFL defensive schemes is also likely a challenge.
Now, what do you want in a backup QB? A game manager to run a low risk scaled down playbook (i.e. a highly paid ball hander-offer who throws 15 times a game) or someone who brings continuity to how your #1 plays in style and scheme?
In short, if a team is looking for continuity, then in my opinion Eric’s best potential fit in the NFL would be the Seahawks, Panthers or Ravens because of his similarities to those starting QB’s personalities and team’s offensive style. He is a smash mouth kid and would fit best on a quasi-running smash mouth team that doesn’t mind a running quarterback.
