It's you who is a fool, my guy. There is no part of putting together a championship-winning roster that is luck. Luck comes into play in the actual games, the bounce of the ball, the shots you make or miss - but the management side of it, that's no luck. I really can't wrap my head around how you fail to understand that putting a quality team together, and coaching it up, are not matters of luck - the same way that the Spurs trotting out Forbes starting for a season also wasn't luck, but bad roster composition. Seriously, look up "luck" in a dictionary - you use it WAY too overarchingly, and incorrectly.
The Raptors were lucky to have Kawhi force his way out in time to make a bid. They weren't lucky to have constructed an excellent supporting cast (Marc Gasol, Ibaka, Lowry, et al) that could contend, when given the necessary star power. It wasn't luck that made them have excelling defensive schemes and presence. The Kawhi game 7 shot against the Sixers - yeah, that's luck. But putting yourself in a position to be lucky, is not luck, but hard and good work. Understand the difference?
I still don't follow you - which part of this is "luck"? If you're not sure whether the player is worth a max, you don't preemptively max them (THAT is bad FO job), you play out the season and then reassess whether he's worth that max. Yes, another team might've tried to pry him away with a max offer sheet, but had the Wolves played out that season, they would've known that letting him walk was the better option. Again, no luck whatsoever - just (bad) FO work.
Injuries lowering the amount of a contract is not luck........ My god. What a guy. What's your point, that the Raptors are "lucky" that OG got injured? You think they'd rather he gets injured and a lower contract, than no injuries at all? Backward-ass view you got there. And again - OG could've well bet on himself and play out the season. There's no luck to be had there, both parties agreed to that contract, and it's a great one (something you've consistently failed to adress, of course).
Related question: who's a good FO in this league, right now? Do you even think a FO can be good? Like seriously - you say the Warriors, Raptors (so the latest champs) are all luck, no work. Do you even contemplate such a thing as a good FO? If not, why do you think the Spurs FO is bad? Can't have it both ways...
