You are delusional. Comparing two leaders who was known to rise to the occasion(past tense, they are old now) & a player who has almost always lead the team to an early exit in the Playoffs?
Same outcome in your mind. Duncan & Kobe may complain, but no, lack of whistle on little body here & there play could not take them out of their game.
You know why Anthony's teams were eliminated early in all those years (except 2008/09 where they got to WC finals and were 2-2 against very beatable Lakers team, but then George Karl play offs coaching happened)?
Because Nuggets were a very poor ran franchise (in 46 seasons they got to conference finals 6 times, losing 5 of them) until they got the right guy as GM (Masai Ujiri), who made all the good moves (Melo trade, Felton trade, Nene trade, getting involved with Howard trade to get Iggy, good last few drafts) and have good foundation and cap space for the future.
You know how many times Denver Melo's temas were favorite in playoffs while he was there? None.
You know what Kobe Bryant achieved after Shaq went to Miami but before Jerry West gift-wrapped Lakers Pau Gasol (very similar trade to Kevin McHale giving away KG to Celtics for almost nothing)?
2004-05 : 34-48, didn't even make playoffs
2005-06 : 45-37, 4-3 first round loss to Phoenix with famous "Kobe not taking single shot in 2nd half of deciding game 7 because he was so mad" which lead to 31 point loss
2006-07 : 42-40, 4-1 first round loss to Phoenix, again!
Then BOOM, Pau Gasol comes to Lakers and they are back to contending status. Even though in those 3 seasons Kobe was playing out of his mind it didn't matter (check his stats from that era, especially advanced stats like Usage Rate, Win Share, True Shooting Percentage etc).
Tim Duncan situation is completely different. San Antonio had enormous luck on winning the lottery in single season when absolutely all the players were injured (David Robinson, Sean Elliott, Chuck Person, Will Perdue, Charles Smith), they fired Bob Hill (who famously flamed out during series against Jazz year before which they should have won) hiring Gregg Popovich (just one of the best coaches in NBA history, who btw was Teams GM and he fired Hill making himself the HC after promoting RC Buford to GM position, only one of the best GM's - HC combo in all pro sports) then selecting best PF in history of the game of basketball. You think Tim Duncan would have been so successful if he had been selected by Vancouver, Toronto, Golden State or New Jersey? So who is delusional?
What is Melo working with in NY? Team that is build around 3 point shooting and his or JR Smith iso plays with suffocating defense (staple of Mike Woodson coaching). NY had for years situation so awful that being competitive (2nd seed in East) is an achievement in itself (one of the worst owners in James Dolan, GM's like Scott Layden and Isiah Thomas for many years).
Again, Melo took team that plays heavy minutes to Jason Kidd (64 years old), Kenyon Martin (out of the league 2 months ago), Steve Novak (I have similar defense on court), Raymond Felton (so fat that he was billed "mr. one more cupcake" in Portland last season), Amar'e Stoudemire (ooops, he doesn't play because his knees are in so bad shape that no company wanted to insure his crazy big contract, basically untradeable at this point), JR Earl Smith III (one of the craziest players/people since Vernon Maxwell), Pablo Prigioni (36 year old rookie), Chris Copeland (29 year old rookie), Marcus Camby (guy who was starting C in last NY Knicks finals appearance in 1999) and Iman Shumpert (their defensive anchor besides Tyson Chandler who had the same injury as Derrick Rose and is not even close to being 100% healthy).
So yeah, a real juggernaut of a team eh? But of course it is Soft Melo fault and I am delusional.
