When Draymond was making All-NBA teams he was one of the best 4 players on the best team in the league and he was a DPOY candidate. That doesn't seem unreasonable to me.
The nature of basketball is such that for the vast majority of players, even many of the most talented ones, the team context determines a great deal of a player's value. Only a handful of players in the best league in the world can really claim that their value is not dependent on the players, system, coach, etc around them.
For that reason, the fact that Draymond no longer looks like a star when he doesn't have star teammates (and by the way he's got significantly more miles on a body that he's never taken great care of), doesn't lead me to the conclusion that he never should have been considered a star in the first place.
Why do you think Smart has never even received real votes for all-NBA teams or all-star games even when he was a star role player on teams with really big win totals and/or making the conference finals. Is it just the difference between us making the finals versus conference finals? We could maybe throw out the one DPOY year for Green cause obviously Smart has never been there, or in that conversation. He was making all-star games when he was a first team all defense.
Smart isn't as good a defender as Green was and Smart had no where near the counting stats that Green did. I mean in 15-16 when Green was 2nd Team All NBA, he averaged 14 ppg, 9.5 rpg, 7.4 apg, 1.5 spg, 1.4 bpg, shot 38.8% from 3, 53.7% from 2, and 69.6% from the FT with a TS% 58.7. Green played just under 35 mpg and started 81 games that year and the Warriors won 73 games (way more than the low 50's the C's have been winning of late). Smart has quite simply never come close to any of those numbers (except the SPG and FT%). Green could then carry that peak year and live off of it for years (so to speak). Heck Smart is mostly a bench player. An elite bench player, but still a guy that generally doesn't even start for the team.
At the end of the day Draymond Green was quite simply a significantly better player than Marcus Smart has ever been.
