I had Hoyer as a 1/2 point fav. Jimmy G at 2', max 3. Not the same but, yes, close. For all the hype, Jimmy G really hasn't proven much. He has certainly proven none of those things I listed for Brady.
It may be a small sample size but Jimmy and Hoyer did play for the exact same team this year and the results were drastically different. That alone probably speaks to the fact there is more than a 1 point gap in the spread between them.
I can only speak for myself but if NE was only like -4 or -4.5 or less with Jimmy at QB vs JVille, I would want to bet them. I think he would be good enough to get NE in a game flow positive situation where they have a lead, can run the ball, Jville pass rush can't peal back and JVille has to throw the ball. With the Jags, so much of it just comes down to how the game is played since they are so 1 dimensional. If it's close or they have a lead, they're built to play like that. If they get behind and have to throw and have to stop the run consistently, they aren't built to play like that.
So he might not be Brady but I do think he'd be able to put NE in a spot where they can still do a lot of what they wanna do, thus why i said around 5.5ish. Maybe it would be a little lower like -4.5ish but I'd like NE there like I said.
And if NE was only -2 or -3 with Jimmy at QB vs Jville I feel like that would be a spot I'd backup the truck.
