Colin Kaepernick: D-
Kaepernick has been known to rebound from a bad outing, but this is the first two he had two consecutive games that were poor. He was unable to find receivers and if he tried the run, the Colts would stop it. It wasn't until garbage time where he padded the stats to be have more than 100 passing yards. The reason his grade isn't an "F" is because his supporting cast failed to help him (see below).
Running Backs: B
Frank Gore was averaging 7.5 yards per carry with 82 rushing yards. Kendall Hunter had a 13-yard touchdown run but was ineffective otherwise. Unfortunately Gore wasn't utilized much after the first quarter.
Wide Receivers: F
Anquan Boldin had five receptions for 67 yards, but everyone else failed to support him. It wasn't until after the two-minute warning in the fourth quarter where Kyle Williams had his first reception. Marlon Moore and Quinton Patton were used sparingly, but both players were targeted only once. The wide receivers were the major reason Kaepernick was unable to make plays.
Tight Ends: F
Like Williams, Garrett Celek caught one deep pass in garbage time to pad the stats. Vance McDonald had only one reception for six yards the tight end position was ineffective in the passing game. This game showed how valuable Vernon Davis is to the team as he was nursing his hamstring injury. Blocking was subpar from this position.
Offensive Line: A-
It wasn't until late in the second half where we saw the offensive line crumble. The running game was effective in the opening quarter and holes were created for Frank Gore. This unit was the one positive offensively because Colin Kaepernick had plenty of time to pass. There were two coverage sacks allowed and several other times where the quarterback was forced to scramble. Overall, it was a great day in pass protection and run blocking for the offensive line.
The offense was smooth on the opening touchdown and the question is, why abandon the run? Frank Gore looked great but the 49ers chose to switch into the pistol offensively and became more pass happy. It's well documented that Gore is a down-hill runner and they failed to continue pounding the ball down the Colts' throats. They looked effective when going off tackle or running simple draw plays but became so ineffective.
Only one read-option was called where Kaepernick held onto the ball, but was tackled almost instantly as the defense knew it was coming. The 49ers became pass-oriented which takes away from the identity that Frank Gore was built for. Their rhythm was out of sync when Kaepernick couldn't find an open receiver and needed to improvise on the spot.
