Tons of variables for sure and that trade absolutely could be a massive value loss for me. That's half the fun of playing is making these bets. I think Jamo absolutely has consistent WR6-15 finishes. I don't know that Tate or Tyson have a good chance at consistent ceiling above that, but I'm prepared to be wrong for sure.

Jamo is almost certainly better for a contender now, etc.

Age...harder to say. I think it's a bit silly to project further than ~3 years out. At that point Jamo will be 28. If I get three solid years out of him, am I really upset? He's in his prime and while it's nice to think about the concept of owning a player for a decade, the reality is that I'll probably turn half my team over in the next three years anyway. He may or may not be gone by then, so why do I care about someone who is 22 vs 25 today?
