Right, so five things all have to go the wrong way for things to not be looking good for Danny, which means his job is not under much threat at all.
One by one:
1): I don't think the expectation is that BOS will get past CLE till LeBron leaves, with or without Kyrie. LeBron is that good. If we happen to get past CLE with LBJ, more the better. However CLE is telegraphing a rebuild by trading two years+ of Kyrie for one of IT4 at a low salary along with a high draft pick, so CLE seems to be on the way down just as we seem to be on the way up. A big turnaround could happen for CLE if they trade the BKN pick for a superstar and hope that it makes LBJ want to stay, but it doesn't seem many teams would be interested in sending a superstar to CLE, and it seems LBJ is already packing his bags for LA.
2): It's definitely a much better scenario for Danny if KI stays long term, but in the end, that's up to KI and Danny can say "I took a shot and KI just didn't want to stay".
3): This is more of a risk to Danny and Brad in my book because bad chemistry can make the whole team suck quickly and heavily, a true 'poison the well' risk being taken here.
4): The owner is signing off on the deals so he'll deal with the tax. I have a hard time seeing Wyc sending Danny packing, except under extreme duress.
5): Winning the EC is within reach when LeBron leaves CLE, and I'm all in on him going to LAL in the off season. If not, then Danny has yet another get out of jail free card to play -- "LBJ stayed, who knew?"...
My epic meltdown involves all of the above going badly, plus the recent high draft picks and the upcoming ones missing badly. A streak of bad drafting when you hold so many high draft picks will put any GM's job at high risk regardless of the relationship with ownership and the track record.
