I have said EJ looks better and improved, but still a D student. TT has shown me more.
Who would we get? I don't know, I'm not a GM, but I suspect that we could find someone closer in style to TT as a backup. I think having two statues as his backup, and one who can't throw more than 20 yards down field, with the other who can only read one side of the field and only the first read isn't going to get you far.
