I was thinking of this very question since yesterday's Xavier game. Great answers.
I don't go as far back as Paultz but saw him as a pro. I think the general consensus was that if not for the period in the ABA where he continually improved, would not have been an NBA center. So I would say right now as a collegian Soriano is better than Paultz was at St. John"s.
LeRoy Ellis was a decent pro and legit big man. For this conversation I'd only include true centers and guys I've seen.
Jeff Allen - competent college center. Formed good tandem with Wennington. Avg 5.9 ppg 4.3 rebounds, but 10.6 ppg 6.6 rpg as senior starter. 3rd round nba pick.
Bill Wennington - solid center at sju who competed well against Ewing. Could shoot, run the floor, play defense. 1st round nba pick. 12.5, 6.4 as senior, 8.2 ppg 5.2 rebounds overall.
Jayson Williams - good college player, better nba player until injury. Avgd 14.9, 6.8 over 3 seasons but 19.5, 7.9 as junior. Injured ltd sr yr to 13 games. Still nba 1st round pick.
Zendon Hamilton - solid college career but could not live up to very lofty expectation of eventual ncaa contender. Athletic center. Avg 15.9 ppg 8.3 rpg. Played parts of 5 nba seasons. Avg 20.8, 10.3 as soph
Rob Werdann - very skilled player especially for a big man. Defend, rebound, pass, score down low and mid range, second round nba pick. 9.7 ppg 7 rpg at sju. Parts of 3 seasons in nba.
Chris Obekpa - shot blocking machine avgd 3.4 blocks over 3 year career. 4.0 ppg 6 rpg.
Lamont hamilton - 11.8, 6.6 over 4 years. 13.4 ppg 6.5 reb as senior. 6-10 but more of a forward. Suffered being part of dismal norm years.
Wayne McKoy - most hyped center in our history. As close to Felipe as anyone we recruited. At 6-8 and not ever in top shape, college career couldnt come close to expectation of next jabbar as a 7th grader. Still, 13.0 ppg and 7.0 rebounds over 4 years was no slouch. Tandem with pal Reggie Carter and strong cast of some good johnnie teams. 3rd round nba pick. High pt 14.9 ppg 7.8 reb as soph. So heralded looie hired willis reed to school him.
Joel Soriano - has averaged 10.0 and 8.5 reb over career. Avg 15.2, 11.9 last season. Meteoric improvement.
Ok. Subjective ranking
1. Jayson Williams
2. Soriano
3. Wennington
4. Zendon Hamilton
5. Wayne McKoy
6. Lamont Hamilton
7. Jeff Allen
8. Chris obekpa
Not quantitative and based on their high point of their career.
Not a bad list but shows how hard it is to find true centers.
