Nix vs. Mahimes Narratives

Watching this Texans/Chiefs game, the narratives could not be more clear in my mind.

Nix: Only shows up in the 4th quarter/overtime. Needs to proven it in the other 3 quarters

Mahomes: He shows up when it matters most

Don't get me wrong, Mahomes has the history and pedigree to get the cred obviously. But why can't folks just be happy for Bo instead of putting him down? (With the exception of Kay Adams lol)
