San Francisco 49ers head coach Kyle Shanahan has done an amazing job this season. Improbably, he has guided his team to another appearance in the playoffs, and if the Niners win their next two games, they will have the No. 1 seed in the NFC.
However, he has one issue that he needs to clean up before the playoffs: his challenges.
On Monday night against the Indianapolis Colts, Shanahan made two bad challenge mistakes. He challenged what was clearly a catch by Colts wide receiver Michael Pittman and lost a challenge and a timeout as a result of that poor decision.
