I see. You will be revising your thinking at some point before next April.
By the way, you're off by $1 mil if overthecap is correct, but that's OK. The difference between keeping Rodgers in 2021 and cutting him is $22 mil in additional cap by 2022. Having his services at that cost for one season is a steal.
There's something you might have overlooked. $6.8 mil of that savings is in roster bonus due on the third day of the league year. That was March 21 this year. Good luck making that call by that time. H*ll, at this stage Boyle would be the first guy off the bench if Rodgers was injured. That's what I thought might be the case at draft time and I've heard nothing to change that opinion. He's got mechanical issues with his footwork, for gosh sakes. He's at the stage where his coach is asking him to "trust his instincts".
That trust might not be pretty either once he gets there and there won't be much opportunity to find out by next March.
Right now Mr. Matt LaFleur is thanking his lucky stars for having the starting QB he has. Book it. And he'll be thanking them again come next March.
I don't know if you think Love is the second coming of Pat Mahomes (he'll never be close to that), or even the second coming of robo-Goff (which would not get you where you want to go), but right now you have no evidence he won't be the bust that most QBs taken at this spot turn out to be.
