I honestly don't know. You seem pretty confident. I just don't know how to predict these things at all. They seem pretty random to me, and the exceptions are not the general trend.
But there may be players more or less likely to age better than others, and that's what Hoyer seems to be making a bet on, but it's still a matter of probability and not certainty, so we just have to see.
Hoyer is far smarter than any of us here combined and his success rate with significant signings has been astonishingly good, which gives me some comfort he knows what he's doing here.
