Kyrie is 4 years younger.
3 years. 
Many others have said it, but man, you have always been one if the most even keeled, and rational posters on this board, but the Kyrie trade has you trippin'.
Because I corrected an oft-repeated factual mistake?
There's a three year age gap.
OK 3 years. Making him a whole max-contract with player option younger than IT.
If you could get IT's productivity for 5 more years versus 2, would you make a trade for that? Because that is what this is all about.
It's more like IT's production + Crowder's production + Zizic's production + BRK pick's production.
But, that's just rehashing the trade.
On topic, I don't think Danny would have walked away from a healthy IT. I get the age argument, but Danny committed max dollars to an older Al Horford.
I agree Celtics overpayed for Kyrie. Cavs got enough instant impact players to comp for Kyrie whether they have his clutch factor or not. Cavs won't feel the hit as some project.
With that said, I think in a dissecting trade standpoint, ofcourse we lost the trade. I also think the over pay was to have a clutch superstar on our team. We completed the path to Lebron in the Conference finals. Hayward is not confirmed to lift us any farther . He is though confirmed to be an efficient high volume wing on our team.
With all we traded, our asset stash is strong and. We have strong projections in player development. Ainge is gambling heavy and I dont blame him.GS set a standard.
