No More "Undersized" Power Forwards
Once upon a time 6'7, 6'8, and even 6'9 power forwards were considered undersized...Reason being the league was filled with power forwards 6'10 & up, but now not so much the case....The majority of power forwards in the league are 6'8, 6'9 which now I guess is the standard height for the "4" spot...6'8 power forwards: Kenneth Faried, Tristan Thompson, Michael Beasley, Elton Brand, Jared Sullinger, Anthony Bennett, Derrick Williams, Thomas Robinson, David West, Tyler Hansborough, Zach Randolph, Patrick Patterson, Marcus Morris, Mike Scott, Thaddeus Young, Anthony Tolliver
Notable 6'9 power forwards: Kevin Love, Terrence Jones, Darrell Arthur, Blake Griffin, Markieff Morris, David Lee, Josh Smith (although he's playing small forward this season), Carlos Boozer, Taj Gibson, Ed Davis,
Paul Millsap is listed at 6'8, but he's really 6'7 that's why I did list him...The same holds true for Brandon Bass, and "Big Baby" Glen Davis, who's really 6'6...All in all still proves my point the power forward position is getting smaller, with exception to LaMarcus Aldridge, Dirk, Duncan, Anthony Davis, Cody Zeller, Josh McRoberts, Chris Bosh, Amir Johnson, Jason Thompson, and etc
Paul Millsap is an undersized Krypt.
If you're going off how tall guys really are, and not their listings as you're doing here in some cases, you might find that there never were many 4's 6'10 & up.
TOP TIER PFs
Josh Smith (when he plays PF)
(until recently: Kevin Garnett)
All the top tier PFs are 6'9+. You can make a living being a 6'8 PF, but it won't be easy. Of all the 6'8 PFs, only Randolph has ever been considered top 5 in his position. However, I'd rather have an intense 6'8 guy like Millsap, than a 7'0 passive player like Bargnani.
Beasley = Tweener
Williams = Tweener
Bennett = Tweener
Morris = Tweener
The reason why they're tweeners? They're 6'8 or under.
I find it funny how people like to exaggerate to make an argument. These are some sizes w/o shoes (usually 1.25'' or 1.5'' is added for shoes).
Glen Davis 6'7.75''
Elton Brand 6’8.75''
Kenneth Faried 6'6''
Kevin Love 6'7.75''
Paul Millsap 6'6'.25''
Thomas Robinson 6'7.75''
Carlos Boozer 6'7.75''
Anthony Davis 6'9.25''
Blake Grifin 6'8.5''
Michael Beasley 6'7''
Josh Smith 6'7''
So... I don't really care for measurementes with shoes, because sometimes players use taller shoes. Sometimes players have a type of body that make them look shorter (or taller), like Elton Brand who has a short neck and was said to be 6'6'' before the draft... or Durant who looks like a seven-footer (he measured 6'9'' w/o shoes but may have grown).
Anyway, it seems we can conclude 6'8'' w/o shoes is the standard measurement for PF's... there are few exceptions like Millsap or Faried. I don't think 6'8'' w/shoes could be considered undersized, though; because lenght and athleticism can easily make up for 1 inch of size. However, if I were in a decision-making position, I'd consider standing reach to be a more accurate measurement for big men.
