Let's say for the next 3 years, Howard plays on average 65 games, and we'll go by a lower base statistic of his annual career rebounds 11.2 RPG. 11.2*65 (3x65= 728) adds up to 2,184 rebounds.
It's not that far beyond belief to think Howard could surpass and get up to top 10 all time rebounds.
If that happens, then he's clearly gonna be a HOF, without a doubt. His resume has been pretty impressive.
