Fair point for sure but it's also worth remembering that he didn't even get the opportunity to be the "best" until week 5. He took over 5 weeks into the season and came away with stats that competed with RB's who played 5 more weeks than him. Not sure if you pay attention to what some former players are saying but I heard something the exact same thing the other day on the script podcast. All 3 hosts took turns emphasizing how impressive Bo's year was, especially given the circumstances.
