In year two Josh Allen was in one of the better programs in the NFL, Mac was playing for Bozo the clown. Here are their passing stats through two years:
Mac was better, he was better especially considering Allen was playing under optimal conditions in year two and Mac was playing under the worst conditions. Mac passed more, more accurately, scored more, had a higher efficiency rating and threw better downfield in yards per attempt.
Let's pretend for a moment Billy O'Brien is great at his job and gets the most out of Mac and the offense?
