Topics like this are why other fanbases and nba fans in general call us delusional. There's a reason Simmons was the #1 pick. True, his attitude and work ethic might not be great, but at the end of the day, talent wins out. And he's got plenty of it, and plenty of high end potential too.
this explains why simmons was the #1 pick. but it also seems to assume that being the #1 is proof of these assumptions. history speaks otherwise.
most #1s do very well, but not all. and a not insignificant number of #1s turn out to NOT be the best from the draft after a few years.
so, it is too early to decide this debate.
EDIT to add a few examples of #1 =/= best of the draft.
Noel (#6) > Bennett (#1)
Cousins (#5) > Wall (#1), debatable, but yes for some minds
Curry (#7) > Griffin (#1)
Westbrook (#4) > Rose, (#1), debatable again, but arguments can be made
Durant (#2) > Oden (#1)
Aldridge (#2) > Bargnani (#1)
Paul (#4) > Bogut (#1)
Pau Gasol (#3) > Kwame Brown (#1)
I had a thread on here and basically since Shaq in 92 the drafts where there was a consensus #1 pick that player was the best player taken in the draft except for Kobe over Iverson, Westbrook over Rose, and Durant over Oden (though Rose and Oden's injuries will always be a whatif and make you wonder as Rose was a league MVP and Oden showed immense potential prior to the injuries). And even in those years, injuries aside, the player taken #1 was no worse than the 2nd best player in the draft. In the drafts where there wasn't a consensus #1, the player taken #1 was almost always not even in the top 5 best players taken in the draft.
Simmons was the consensus #1 player. Barring injury that means he will almost certainly be no worse than the 2nd best player in the draft and will most likely be the best player taken in the draft. This makes perfect sense, when all the scouts agree on a player, that player is going to be pretty darn good (I mean Iverson and Rose were league MVP's for crying out loud, they just had a guy that was better than them in their draft).
What the research also showed was that all #1 picks aren't equal. I mean everyone knows this, but for every Lebron James there is a Kenyon Martin. Both consensus #1 picks and both the best player from their draft, but a very significant difference in their overall career trajectory. So using historical metrics, Simmons, barring injury, will very likely be the best player in his draft, how good he ultimately comes is certainly unknown though.
