NE defense for QB

My team is pretty deep but I’ve been streaming QBs and it’s cost me at least two wins. 12 team league that for whatever reason has a lot of stashed QBs this year. I could trade a wr4 or 5 and NE defense for either Kyler Murray or Watson. Am I better off rolling the dice with streams/hoping for a waiver drop, or should I lock into a top QB before NE gets a tougher schedule? Otherwise it’s rivers, Stafford, Jimmy g, etc.

Did you just said Jimmy G??? Dude!! Get him now and keep your defense!!!

I already went to that well once vs Pittsburgh and he scored 9.x points for me. Maybe things will improve, but I’m nervous they’re going to run in all their points this year
