I like and can appreciate the talent of borrow. However, much of his success was coaching.
Its not common coaches allow their QBs to sling like that even of they can... The coaches generally mitigate risk. A player cocky enough are a dime a dozen if left to their own devices but a coach isn't.
I wager another will emerge and almost as good as burrow was. But man, that kid was magnificent, and those receivers played just as hungry... The entire team played hard and above their station on paper. That, y'all, is coaching as much as talent.
