Wow, people would actually pick Crum? Based on Crum-backs a few years ago, I guess.
Give Ford an offence suited to his abilities (2 reads & run or ride and decide) & don't try to turn him into a pocket passer. Let him do what he does well and reduce the number of dropbacks and reads he has to do. He would be at least as successful as Streveler, although that's a pretty low bar.
