The Bears have struggled mightily on the offensive side of the ball, and a big part of those issues have stemmed from their offensive line.
They recognized that the performance of their offensive line was less than ideal in 2019, so they fired offensive line coach Harry Hiestand and replaced him with Juan Castillo. However, they decided to only add one new starter to their line, replacing the retired Kyle Long with Germain Ifedi, who was signed to a one-year, veteran minimum contract.
As of this writing, that decision to neglect the personnel perspective of the positional retooling is coming back to bite them.
