You mean where he went 0-3, averaged 186 yards passing, and had just one TD pass? Yeah, I was on the edge of my seat. And apparently the Broncos were encouraged as well, given that they decided to mortgage their future to upgrade from Lock and his cheap rookie contract.
Your numbers are correct, but you've forgotten "it's a team game".
Vs LV, Lock did have only 153 yards, no TDs no INTs. Carr had 1 TD and 2 INTS.
Vs LA, Lock had 245 yards, 1 TD. Herbert had 232 yards, 2 TDs...not INTS for either.
Vs KC, starting right tackle slipped and fell walking into the ballpark(believe it or not).
Lock ran for 2 TDs vs KC, had a long pass dropped by Jeudy, Gordon's fumble was caused by a missing right tackle.
Also, Herbert had better receivers. Mahomes had much better receivers.
If Lock had been the winning pitcher vs KC(never mind Bolles, Simmons, Fant...anyone else), would you be feeling better?
