Sorry can you quote the strawman for me so I can see what you were arguing with?
Who said "every player past 30 is devoid of any value, guaranteed to imminently fall off, etc?"
My point was clear as day. Trends suggest Slavin will sooner rather than later fall off. If he doesn't, good for him, but the math is on my side.
No one can predict the future, but we can look at recent historical trends to determine what is more likely to happen.
Sure, Slavin *might* be a rare physical exception (this has nothing to do with skill or talent) and remains as elite as he is now into his mid-late 30s.
Where your argument falls apart is that you're assuming it's reasonable for a team trading for a player to act as if this statistical improbability you seem so certain of, is *absolutely going to happen*
