If he can throw even remotely, he would be an excellent backup for us.
Edit: you can disagree if you want to, that's fine. I'd like to know which other backup QB is out there that they can use in a similar way that they use Allen. If they had to use Keenum last year the entire offense would have had to change because Keenum can't run. Physically, Newton is what Allen is going to become if they keep using him the way they have been. No he can't throw well anymore, no backup you are signing will throw at an elite level. Newton can at least run.
