Wrong.
Emery inherited a team with an aging defense and a weak offense, but immediately spent big on the offense while bringing in a gimmicky HC without recent ties to the NFL. At the end of Emery's reign, the defense had gone from a respectable but old defense to perhaps the worst defense in NFL history while special teams was a joke and the offense had dragged the whole team to the point that the team itself had become a cancer.
During Pace's handicapped reign (yes, he is now out of his handicapped reign as he has been able to hire the people that he wanted), Fox was brought in to be the temp coach during the main portion of the rebuild. Fox's main attribute was being able to bring in coordinators that were actually good. It was because of Fox that Fangio is now the DC of the Bears. Gage was also a Fox hire but his one-year success got him a HC gig, but Fox was unable to replace him with a decent offensive coordinator probably because he tried to push his ultra-conservative offensive thoughts on them. Under Pace, the NFL worst and oldest defense became a top 10 defense while completely shifting from a 4-3 to a 3-4 which took time, the offensive cancers were removed from the team while the offense became considerably younger. Alshon was offered a better deal than he accepted with the Eagles but he decided to not accept it because he just didn't want to be a part of the team (can't force players to stay if they don't want to stay). Some older but good players were let go because they would not fit into the future of the team.
As for the Cutler and Glennon signing, only an idiot would think that the Glennon signing was worse. The year after Glennon was way overpaid, he has zero affect on the current Bears team. Cutler was negatively affecting the Bears for many years, including some of Pace's years as GM. The Bears' record under Pace was affected by Emery's decisions.
Under Handicapped Pace, the Bears have become a destination of the top offensive minded HC available and free agents, the team has gotten significantly younger, the defense has become a 3-4 defense while becoming younger and a top 10 defense, the offense has drafted some play-makers (in fact, they have been very successful recently in the draft) with a potential franchise QB added and has gone from having a cancerous roster to a much more positive roster.
Now the Post Handicapped Pace needs to show results.
