I don't think they win this year, they may go out this week. But losing AB and Godwin may actually be good for them because the team is finally playing Brady-ball and taking what they're given. They have a whole slew of #3 and #4 WRs in Perriman, Johnson, Miller and Grayson. I think they'll be fine--the key is signing Evans and keeping the OL intact.
And with all their injuries on defense, it also looks like they can stand to lose a few there and still be good. I'm not saying they will ever win anther SB with Brady, but with Brady you always have a chance.
He's playing well, he's moving well, he's throwing well, so he stays. Even if they win the SB. Who was the last guy to win 3 in a row? No one? Oh--reason enough to stay.
