I don't disagree. But I'm sure there will be some split opinions. It was an easier argument to shoot down in 2008 because of how much younger Brady was back then. Now that he's 8-years older, finding a successor is a reasonable thing to wonder about, and I'm sure it's going to be tougher when that time eventually comes
With another 3-4 years hopefully potentially in the tank for Brady, I think they'll ride this out and use Garoppolo to get them some currency to hopefully add some draft picks one more time for him. I think the only way they'd move him is if he really dropped off this year and we saw his turnover numbers skyrocket into double digits. INTs and completion percentage drop offs are generally the key indication of a QB's ability to see things and react quickly, so that will be the big thing to watch when he comes back. Hopefully we'll still have quite a while before that happens. Although I'm sure by Week 9 - essentially around the bye week - this thought will either die off, or gain steam. I'm sure it will be an interesting year.
