Yeah that was a good read. I don't agree with all his conclusions, but wanted to total things up below as it were, in order to demonstrate the obvious:
First play reviewed Tavon is not really an option because he's covered. As usual the short comeback negates his speed since the DB has help over the top and is expecting it. Looks like SCHEME is to blame.
Second play the line didn't pick up the stunt correctly, however the outlet to the back was there for an outside shoulder throw. Top QBs would get it out, this is why playing with a backup is so difficult. QB IS AT FAULT here, this is a big boy league, gotta be able to get it out quick and on target to the outlet on the blitz.
Third play diagnosis is all wrong IMO. Feeding the ball to Tavon based on the pre-snap look was idiotic. Looks to me like Case read that the LBs were coming, and tried to get the ball to him as the outlet. Had the LBs come it would have worked, although the safety might have killed Tavon which is why he changed his course I think.. Regardless, however, where Case should have gone with the ball was the left sideline, where he had the matchup and separation at three yards!!!! That one was all ON THE QB. All Case. You're talking potential TD versus possession change at midfield.
Fourth play the throw was late, all Case once again. He also threw a terrible ball, which is dangerous on that type of route where it's critical you not only keep it low (which he did) but put it on the receiver (which he did not). Kind of ball that can get tipped and intercepted. But again, it is ON THE QB.
Fifth play is where Case should have been pulled man. Seriously, it makes me so effin angry that the guy was left in there. He had a 100% TD to Tavon but elected for the safe throw to Quick. And of course Quick effs it up. But it should never have gone to Quick. A starting QB, hell even a backup QB would throw the ball to the guy slicing deep with green in front of him. Another mistake ON THE QB.
Sixth play is the Havenstein whiff. That one's ON THE OL. That said, Tavon is wide open right on the other side of the OL for the early half of the route, but I won't blame Case there since seeing a guy comin in like that just wrecks things.
Seventh play GRob gets faked out by the blitz threat and leaves Higbee alone on a mismatch. ON THE OL.
Eight play Case is late to the TE with the ball and it gets picked. This is the kind of play that, in a game, gets a QB an early shower. Absolutely bush league man, the type of throw a rookie would make, or a guy who has no right to be playing starting QB. ON THE QB.
Ninth play Case has the TE open but misses his window, and dumps it in the vicinity of Tavon due to the rush. ON THE QB.
Tenth play Niners bring it and get a runner through, but of course Case misses the window on an open Kendricks yet again, then feels the rush and can't make the throw to the open RB. Not gonna get on the OL here, it is the responsibility of the QB to get it out. ON THE QB.
Eleventh play is all on Britt. First he made things hard on himself, then he dropped the pass. ON THE WR.
So of the 11 worst plays from that game, 7 were directly attributable to Case Keenum and of course included the two plays that resulted in interceptions.
Of the remaining 4, a couple were on the OL. One was on Britt. And one was scheme.
Now of course we can all watch those clips and come to slightly different conclusions overall, but it is clear where the problems primarily lied. And don't even get me started on how Fisher elected to not pull his boy Case.
