The Bears are already near the top of the league in available cap space for 2018, with about $50 million to spend. And they’re likely to have a lot more space available when they get done cutting expensive veterans. Mike Glennon has a team-high cap hit of $16 million for 2018, and it goes without saying the Bears will cut him. Signing Glennon last year was a huge mistake by G.M. Ryan Pace. But a less-discussed mistake for Pace was signing wide receiver Markus Wheaton, ostensibly to be Glennon’s No. 1 receiver. Wheaton caught a grand total of three passes for the Bears last season and with a $5.75 million cap hit, he’s almost certain to be cut as well. Pernell McPhee has played well at outside linebacker at times, but his cap hit is $8.1 million in 2018, and ESPN is reporting McPhee won’t be back unless he agrees to a pay cut. McPhee will probably test the market.
