If Brady gives them the home town discount on a one or two year deal, they’ll at least listen.
Their window is right now. QB aside it is the best, most complete roster in the league, and it isn’t all that close. If Brady would go there on the cheap, they might do it. Lance has not played all that much football period, so he is a massive unknown. It really would hinge on Brock. If he keeps this up, then you’re right, they probably would prefer to roll with Brock/ Lance and spend cap on their other upcoming FAs. But they could also bring in Brady for a year to push for a SB, let the young guys learn from him, then have Brock and Lance compete for the job. Frankly, as it stands now they are on track to have a cheap deal with Lance when his rookie deal runs out. Then they will still have Brock on the cheap.
I think it’s 90% that they will spend elsewhere and let Brock and Lance compete for a spot. I think Brady is that other 10%.
I think the odds of Brady coming to SF is basically zero.
1. For one, I think he's starting to actually look his age finally.
2. With Purdy and Lance, they have mobile quarterbacks which is clearly something KS values.
3. KS has some ego about his system and I think he loves all the praise he gets for putting these QB's who aren't marquee guys in great spots and see them succeed. I also think he wouldn't do anything to take away from the defense or other offensive positions.
