In the first quarter against the Jets on Sunday, Colin Kaepernick completed all seven of his pass attempts for 95 yards and a touchdown.
His final stat line: 15-for-26 for 133 yards.
What went wrong? Greg Cosell explained on KNBR 680 on Monday evening.
"I could go through plays guys -- and it's hard for people to see it because the explanation you almost need to see the play -- but there were about three or four plays in the second half with Kaepernick that are just so representative of why he's just not really an NFL quarterback that you can look ahead and say, 'He's part of the solution as we go forward to next year,'" Cosell started.
"There are plays, specific plays, where he just breaks down. Or, he throws the ball too hard, a little bit inaccurately. He's ultimately not a touch, pace and precise ball-location quarterback."
Kaepernick has the ability to opt out of his contract at the end of the season and become a free agent.
He could also opt in but have the 49ers release him before April 1.
There have been several games where Kaepernick put together strong first quarters or first halves, only to struggle the rest of the way.
"He starts breaking down in the pocket and moving when there's absolutely no need to move," Cosell said. "He breaks down plays -- plays that are there ... this is what happens as games progress. He starts out -- there seems to be some comfort level with him as he starts out -- but then as the game progresses, he just breaks down. This continues to happen and I don't know where to go with this.
"I know that Chip Kelly is probably tearing his hair out a little bit because they design some pretty good plays."
