It’s not incredibly likely that the Chiefs turn heavily to a rookie fullback, a street free agent, and a primary passing down back (on the team for less than 1 month) to carry their offense. It is far more likely that they turn to their top 2 all-time quarterback and wide variety of passing weapons to move the ball. Mahomes has averaged over 300 yards per game indoors in his career, and the conditions are ripe to eclipse a total much more conservative than this in week 3. RG prop model was on this and I tend to agree.
