He's produced in Houston possible with an uptick in snaps as he's playing about 60% of their defensive snaps, am not sure he'd get same snap count here.
Herbert is very reminiscent of his predecessor Phillip Rivers in both look great but seemed to lack that end game killer gene, we've all seen it in Brady. Manning, Mahomes and Allen but like you I feel he just lacks something.
To me the biggest thing that killed me with 13 seconds was the dismal display our D showed in OT. You'd think after giving up the FG the D wouldn't want to show we could stop or hold KC to another FG but instead they let Mahomes march KC down the field for the TD.
I know he is but some fans either feel Josh can't be blamed at all for mistakes and others want to blame everything on him. To me there's a middle point and that's where I'm at. I mean I was upset with Josh's interception and near interception but also give him credit for the clutch pass to Diggs on the final drive.
