Well, that last two-point was most likely a gaff by the DC, and they would never have been in that situation if Mahomes had gotten them further down the field before that last three and out.
Mahomes just lacks the experience Phillip Rivers has. Rivers was also without a running back, but if you give him enough time back there he can make anything happen.
You asking or you telling?
At any rate, the picture doesn't seem to have a whole lot of context other than being a ghoulish publicity stunt. Heck, even the photographer seems to have been in on it.
