There's two problems.
1. You aren't drafting a Tom Brady who can cover up everything. And frankly the other teams with good QB's aren't asking their QB's to cover mistakes like Belichick. They just get talent for their QB to play with.
2. Even with a QB, we need WR's and lineman. If you HAVE to make that trade.... you are basically conceding that you won't be picking again until the late third at best. Which means you can't guarantee any quality there.
They are just better off finding a way to lose out.
In fact, and people will hate this, they should probably do something similar to what the Colts did. Drop Mac in the offseason, draft Harrison Jr as a premier WR, go in with a junk QB and get another high draft pick next year and get your guy when you have some talent. Otherwise you are just setting up the next guy to fail.
And for the love of god, get rid of Belichick. He is not the guy to do this.
