Boykin looked pretty much like we expected. Bipolar. He looked very good and very bad at different points in the game.
On the INT, he simply held the ball too long, and stayed locked onto his primary target even though there wasn't a play there. The only way that play has a chance of working is if he throws it before, or right when McEvoy makes his break, or if McEvoy does anything except to just stand there after his break. Maybe, Boykin could have thrown it over the top, but even that would have been contested by Robinson.
As it happened, McEvoy made his break, then just stood there. Boykin, after making the worst play-action fake in history, stared at McEvoy through his entire route. It was so bad that Bellore made a move on the ball before McEvoy finishes his break and before Boykin has even started his forward throwing motion. Once McEvoy stops, Boykin threw the ball, ignoring Bellore who was in the path of the throw. All Bellore had to do was take one step in front of McEvoy for the easy INT.
Regarding the O-line, just stop. If anyone blew protection, it was Graham who completely whiffed on Armistead which ruined an otherwise perfect pocket that Russ could have stepped into. The protection was more than adequate however. The Niners showed blitz with 7 players, ultimately only bringing 5 with Harold remaining back as a spy, and Bowman pulling out to cover Michael on the checkdown route.
Wilson flushed early, but had a good 3 seconds had he stayed in the pocket. He had over four seconds to set and throw, and five seconds to throw it away instead of trying the stiffarm. Being up 21, he had no excuse for trying to make a play. When the Niners brought the 7, he should have thrown it away if he didn't have a hot route likely to be open. Instead, he unnecessarily tries to Houdini it.
Love the competitive fire, just wish he was a little more aware of the situation there and didn't try to be a hero
