With the knowledge that we have now:
- Kyrie Irving leaving for sure now as he's unhappy
- Al Horford leaving, because we're not a contender anymore
- 3 draft picks being used on Langford, Williams and Edwards
In hindsight, should the Celtics have tried to beat the Lakers offer for Davis?
The Lakers gave up:
Lonzo Ball, Brandon Ingram, Josh Hart + #4 pick + '21/'22 pick + pick swap in '23 + '24/'25 pick (= 3 players + 3/4 picks)
The Celtics could have easily beaten that with:
Jayson Tatum, Marcus Smart, Robert Williams + #14 + #20 + '20/'21 Memphis pick + pick swap in '23
Would you have done that with what you know now? Explain why yes or why not.
No. Our circumstances are different to theirs. All the signals indicated that he was going to hit free agency and re-sign with the Lakers in 2020 no matter where he was initially traded. The risk of losing a massive package for a year was too great. People are slitting their wrists about our franchise now, imagine how much worse it would have been if we got Davis for a year, lost Kyrie anyway, and gave up Tatum, Smart, Williams, #14, #20, 21 Memphis and pick swap and he left next year. (note that none of the young guys that Kyrie allegedly didn't get on with are in your deal so they would still be on the team, but even if you swapped in Brown for Tatum I still wouldn't have done it for a year rental).
Lakers have 3 more years of LeBum, they aren't in the running for any free agent, their team outside LeBum sucks balls and they know Davis wants to re-sign. The risk is low. Even so they gave up a lot for a player they most likely get next year in FA anyway. That's the pressure to win now that LeBum exerts, given he's not getting any younger.
As for the Pels, I'm sure they would have taken our package over LA's. Griffin would have considered himself a genius if he had managed to convince Danny to pull the trigger on that deal.
