I'm a big fan of Iggy's game, but I wouldn't go as far as including him in the all-decade teams. I also tried to balance out the teams by including 1 PG and 1 big man in each team.
Steph
Harden
LeBron
Durant
Davis
Paul (the best floor general in the 2010's)
Klay (3-time champ, revolutionized the game alongside Steph)
Kawhi (2-time champ + 2-time Finals MVP)
Blake
Giannis (1 MVP)
Westbrook (1 MVP, out of this world stats, mediocre team success since the big 3 broke up)
Wade (2-time champ)
George
Green (3-time champ)
Boogie (based on pure talent alone)
honorable mentions:
- didn't include Kobe and Dirk cause imo their best years were in the 00's (although they both won a championship in the 10's).
- Dwight Howard (3 all-NBA first teams, 1 all-NBA second team, 1 all-NBA third team, but I just don't like his game anymore. In all honesty, recency bias isn't working in his favour.)
- Melo (zero team success, the numbers are there but I just never liked his game)
- Aldridge
- Marc Gasol (over his brother in the 10's)
- Kyrie (huge clutch shot to win the Cavs their only NBA title)
Keeps Melo off his list for "zero team success", puts Anthony Davis on the 1st team. Nice, no bias here. 
Well, there are not many star players to choose from at the C position whereas there is plenty of competition at the wing position (LeBron, KD, Kawhi, George to name a few). Gimme an elite C who enjoyed even moderate team success during the 10's and I'll put him over AD. At the end of the day, AD and Boogie may were the only elite Centers during the 10's (just in terms of talent). Embiid almost never played. Can't think of anybody else at that level. KAT and Porzingis would have been nice options, but none of them played enough games in the 10's.
Like Dwight Howard? 58 playoff games from '10-'19. Played more playoff games in a single season ('10 or '15) than Davis has played in his career.
I'm just giving you a hard time, but there is serious bias going on.
No ones sticking up for Dwight here, and he's a bum now, but we're talking (just from '10-'19):
2x DPOY
5x All Star
3x 1st team All-NBA
1x 2nd team All-NBA
1x 3rd team All-NBA
3x 1st team All-Defense
3 top 10 MVP finishes (2, 4, and 7). (I think this is a terrible metric, but it's being used by some, so I'll throw it out there).
For the decade (for those listed as F-C, C, or C-F): 2nd in Rebs, 3rd in WS, Blocks, 4th in Pts
Probably should be on everybody's first team.
yeah I totally forgot about him. He should definitely be on a team (and frankly I think I'd put him on the 1st team).
So my all decade teams (holding to their 2 backcourt, 3 frontcourt)
1st - Curry, Westbrook, James, Durant, Howard
2nd - Harden, Paul, Leonard, Davis, Griffin
3rd - Wade, Lillard, George, Aldridge, Antetokounmpo
The interesting choice for me was Giannis or Melo for the last spot. Giannis is obviously a better player, but his best decade will be the 20's and he didn't play for several seasons of the 10's, but at the end of the MVP for Giannis let me bump him up ahead of Melo.
