Here is the difference I see, and it'll be up to Nate to work hard to overcome-
Jeff Withey was a highly rated and highly skilled player in high school in San Diego. He was rated 4-stars, and had offers from some of the highest level programs, including Arizona, Kansas, Indiana, Syracuse, Texas, Boston College, and others.

Withey was the #36 rated player in the country, the #8 best center, and the #3 best player in California in 2008, according to Rivals.
On the other hand, Nate Wells probably wasn't the #3 best player on his high school team. He was not recruited by many schools, and didn't have any offers other than Bradley's. Nate is a classic late bloomer. Hopefully he can develop into a player who can give us solid minutes at center. He has already developed a consistent outside shot, something we haven't had a big man who could do since Chad Kleine, and I have heard he does have good defensive and shot-blocking instincts.
