Yeah you could easily argue that Tim was the most consistently important player to last year's le run. Obviously Kawhi took over in the Finals (also had a great series against Portland), but he wasn't that good against Dallas/OKC. Tim didn't play very well against Portland, but in every other series he was great.
The people who try to use Parker winning FMVP over him in '07 as a knock aren't even worth discussing with. Tim carried us through the first 3 rounds (where we faced our toughest opponents), and then Parker took advantage of a mismatch in the Finals against a team that had a terrible backcourt. While it's generally true, FMVP =/= best player on the team. Parker was nowhere close to Tim in the '07 playoffs.
As for
Killakobe81 's take about IRL discussions - the majority of fans I've come across IRL (and even on the internet) are far too enamored with scoring. You can deride analytics all you want, but the other arguments you hear are just as stupid. I've heard people argue AI as a top 10 player of all-time. In 2012-2013, I heard people claiming Melo was the best scorer in the league and wasn't far behind LeBron as an overall player. The average NBA fan watches their hometown team, and then catches highlights on Sports Center. That's not enough to form an informed basketball opinion about players all around the league. They see a few stats here and there, "Melo is averaging 25 ppg, 3rd in the league!" and then they run with it. If you asked someone at your barber shop who Rudy Gobert was, how many people would be able to answer? How many people would tell you the sort of defensive impact he's having this year?
As for whether things will change regarding Kobe...I'm not sure. When he retires, what are you going to see? Highlights. And in the end, that's the sort of thing that makes Kobe seem so amazing. I mean obviously he is an all-time great player, but if you're comparing highlight reels, he's probably top 5 all-time. 81 points, 62 points in 3 quarters, game-winners, etc etc...fans eat that up, and I don't see that changing. So if you're arguing that those sort of arguments aren't necessarily good, but that they'll continue anyways, I agree. But I don't think the way many fans judge players is smart. Too much emphasis on cliche bull like "clutch moments" and rings. Do those things matter? Sure. But not to the extent people argue.
