I haven't even mentioned wingspan, much less"argued" it.
I haven't said that a 6'-7" guy "couldn't" play center. I simply said that we should be looking for bigger than that if we want to be successful. And yes, 6'-8" and up qualifies as bigger than 6'-7".
It's not so much comparing UNC to ODU as it is comparing a winning formula (one that ODU used to follow - good size inside to complement skilled guards) to ODU's recent/current formula (poor size inside to complement semi skilled guards). At least they appear to have better skilled guards on the way.
For accuracy's sake, UNC who won the national title last season had the following at the PF/C positions (see link below) -
6'-9" Kennedy Meeks
6'-9" Isiah Hicks
6'-10 Tony Bradley
Luke Maye and Justin Jackson are both listed at 6'-8" and playing the small forward position.
You probably didn't follow ODU back during the Mark West era at ODU (82/83 senior year) so I will cut you just a little bit of slack on that Mark West comment. That team had a starting line up of -
C- Mark West, 6'-10"
PF - Kenny Gattison, 6'-8"
SF - Ronnie Wade, 6'-6"
SG - Charlie Smith, 6'-3"
PG - Grant Robinson, 6'-1"
Key reserves were -
C- Clarence Hanley, 6'-10"
C/PF - Horace Lambert, 6'-8"
SG - Keith Thomas, 6'-3"
Now whether the game is or isn't "completely different" since Mark West played, I would take that team any day over ODU's teams under Jeff Jones. Further more, I would like my chances to win C-USA and get an NCAA Tournament bid with that group. The pair of West and Gattison both would go off on guys like Brandan and McClinton inside, and there isn't much that they could do to prevent it.
And 'yes', I do believe that McClinton at 6'-7" was coming in to be our Power Forward, all 200 pounds of him. Sadly so. Believing it doesn't mean it was a good thing.
So without checking more thoroughly, at only 7 guys of your original list of 16 are actually 6'-7" or less while the other 9 guys are listed as being taller than 6'-7". Do you just make stuff up as you go along?
