By waiving Connor Shaw the Bears are going all in with their three quarterbacks
There will be a lot of competition, but not much competing for spots on the Bears quarterback depth chart. By all indications, it does not matter what Mitchell Trubisky does in training camp, he is the backup. Mike Glennon is being paid to be the starter and he has a chance to earn himself a lot of money in the upcoming years by keeping his job as long as he can. Both will be competing, but not for a depth chart spot. Mark Sanchez will be competing as well, but it will not be for a roster spot.
Some had suggested that the Bears may have had themselves some competition at the bottom of the depth chart as well. However, the Bears went out and signed Sanchez this offseason already knowing their status and beliefs on Connor Shaw. Now with Shaw out of the way, the job of the Bears third string quarterback now officially belongs to Sanchez.
The Bears may sign another arm at some point, but they will be well behind Sanchez on the learning curve. While Sanchez gets laughed at and ridiculed, he was still a top 32 starter in the NFL for a small period of time. He is likely one of the 64 best quarterbacks in the NFL which actually does say something when looking at him through the eyes of a third string player.
Sanchez brings tools to the table in the video room and has experienced success and high-pressure situations first hand, something neither Glennon or Trubisky have done. Sanchez will be a valuable third quarterback and now has a roster spot locked in heading into the season. Barring injury, the Bears quarterback depth chart is locked in for the season right now.
