Veteran receiver Keenan Allen offered some insight Wednesday into what went wrong with Shane Waldron serving as the director of the Bears offense.

The Shane Waldron Experience was a brief-yet-memorable one for the Chicago Bears and their fans, and now that he’s gone, we’re learning a bit more about why he didn’t stick around.The Bears fired Waldron after nine games as the team’s offensive coordinator on November 12.

Keenan Allen was a high-profile trade addition with the Bears. However, he has yet to reach his full potential in Chicago. Injuries have held him out of a few games. But in the seven games he has played, Allen has caught 26 passes for 241 yards and two scores. Not as explosive as Bears fans were hoping for.
