Here are the things that I will admit when it comes to Walton

1) One of the greatest college players of all time no matter what the position

2) Was a highly gifted and a talented player who once had the POTENTIAL to be a top 10 center of all time

See what people get confused about is there is a difference between potential to be and actually being something. People will argue well when he was on the court he was great ok well how often exactly was he on the court?

468 out of a possible 820 regular season games over 10 seasons he played in

Which breaks down to 46.8 games per season
Another thing to take note of is the career average of 28.3 mpg

So for the 10 seasons he did play games in a large portion of it he was not even on the court.

Then you have the 78-79, 80-81 and 81-82 seasons he missed entirely so that is another  246 games missed added to the 352 games missed in seasons he actually played games in.

Whether it was from his injuries or his own choice to sit out he actually missed more games than he played in.

Due to his injuries and sitting out his actual NBA accomplishments are pretty thin

1x NBA MVP
2x NBA Champion (1x with the Blazers and 1x with the Celtics)
1x NBA Finals MVP
2x All Star
2x All Defensive First Team
1x All NBA First Team
1x All NBA Second Team
1x 6th Man of the Year

In his 4 seasons he played in with Portland they had a winning record only twice.
In his 4 seasons with the Clippers they never had a winnning season.

So in the 8 biggest seasons of his NBA career his teams only had a winning record a total of two times

Then comes the last two seasons of his career that he played games in which was with the Boston Celtics. By this point he was reduced to a role of 6th man on a team that had been to the NBA Finals in the two seasons prior to him coming. So yes he won a ring but was just a 6th man on a great team by that point.

He was the man in Portland but it was for a very short period of time
209 games- 17.1 ppg, 13.5 rpg, 4.4 apg and 2.5 bpg

He was good with the Clippers but not what he was in Portland
169 games- 11.9 ppg, 9.9 rpg, 2.9 apg and 2.2 bpg

He was a good helper with the Celtics but far from his days in Portland
90 games- 7.0 ppg, 6.4 rpg, 1.9 apg and 1.2 bpg

He was a great talent and had top 10 talent but not top 10 all time for centers when it comes to actual on court accomplishments.

So here are guys over him in no particular order

Bill Russell
Wilt Chamberlain
Kareem Abdul Jabbar
Hakeem Olajuwon
Shaquille O'Neal
Moses Malone
David Robinson
Patrick Ewing
George Mikan
Willis Reed
Nate Thurmond

heck possibly even Cowens, Gilmore, McAdoo, Lanier, Parish or Unseld

Point I am making is that the position of center has a number of people who accomplished more and did more on the court as an NBA player.

There is a difference between top 10 potential/talent and actually being top 10. People are so blinded by Walton's college career and the ability he had that it makes them lose sight of his actual NBA career.

So no he is not a top 10 NBA Center All Time
