HB is mobile enough in the HS games I have seen. Remember Burrow is a 5th year senior. He hasn't always been as he is this year. Development, the right scheme along with a quality roster changes everything. IMO Harrison will have a similar opportunity. LSU has Brady, Bama has Sark, we have Chaney. That's some offensive brain power and expertise right there.
The lesson from this game is for the coaches. Never let your foot off the gas pedal when on O while working the 2's and even 3's in with the starters once you get a good lead. The subs get to experience the speed and execution at a higher level and learn more. Once you get up by 40+ or have a nice lead in the 4th quarter you can make the wholesale changes.
