Bears starting QB got benched, their top two RBs are out (one.on IR and the other on Covid-19 list)... and their OL sucks... but their QB is extremely mobile.
I kinda want to blitz the hell out of their offense, to give their backfield (with a rookie QB and rookie RB) the least amount of time possible to find an open target, either consistently sending 5 guys or sending 4 with a designated spy just following the mobile QB when he runs.
Yes, this could potentially lead to giving up more big plays... but they'll have less time to get those big plays and less communication will be needed with the DBs as it's less zone and more single coverage, and maybe one deep Safety (Savage) to hopefully stop TDs (and yes he got burnt last week with that, but hopefully he's learned and the Bears QB mit not be as good as the Bengals QB, and I certainly don't think his OL/RB are...
But go heavy aggressive at their OL and backfield, and try not to give them time to pick on our CBs.
