First drive. First and 10. Carry by J.Taylor for -1 yard. Didn’t get a first down.
Third drive. First and 10. Carry by J.Taylor for 1 yard. Didn’t get a first down.
So the running game was also part of the reason those 2 drives failed. Agree that the passing game was awful on all 3 drives.
On their very first drive of the game Taylor lost 2 yards on 1st and goal from the 4, then an incompletion, then they gave him the carry again and he powered in for the TD. Not every carry is going to result in a first down, but you don't abandon it, you keep trying (especially when it's working overall).
That first drive you listed started from their 2 yd. line, so running into a pile that knows it's coming generally doesn't result in success. Again, we can throw that drive out due to the unusual circumstances.
The 2nd drive, while still up 10 points, had zero runs and resulted in a 3 and out. Dumb.
The 3rd drive, while still up by 3, had 1 run vs. 4 pass attempts (ended with a sack). Dumb.
You left out the 4th drive, down by 4 but with 7 1/2 minutes left, which was a pass, run by Hines, then an INT. Dumb.
Final drive was classic Rivers dink and dunk with Hines. Not a huge argument here, although Taylor has shown to be very good as a receiver as well (they foolishly only targeted him once this week).
Much more blame lies with the play calling and Rivers than Taylor for this L IMO.
