because of something else? His injured foot made him make worse reads and suckier passes?

Then when we ran a read option last year (not enough, but we did it from time to time), he suddenly was able to move the ball effectively. It was magical last year how you could see it when Ty switched to a read option with a hurry up... It was like the old Taysom came back for a few minutes...

Then, back to a pro style...

Now he is suddenly good again... and made an NFL roster.

Why did Tanner suddenly go from being a Freshman sensation to a player who cannot make any passes and looks lost out there?

It's the scheme and if we fix the scheme, we will suddenly look halfway decent on offense suddenly...
