Newly acquired Washington Wizards center Dwight Howard is already in a war of attrition of his own. The three-time Defensive Player of the Year has upped his defense on his recent beef with Shaquille O’Neal, saying that the latter’s roasts are just based on a “little insecurity.”

Keely Diven of NBC Sports Washington documented Howard’s latest response to O’Neal:

“[Shaq] said something online about the whole rings situation. He got rings, I’m not in his league and all that stuff. But if that’s your only way to come back at all players, then you really don’t have too much to say.”

“I think it’s a little insecurity on his part because people call him ‘Superman’ and they call me ‘Superman.’ But if I’m an older guy and it’s younger players that are being compared to me and they have that same nickname, I want to feel good about it.”

There’s no telling if Howard and Shaq’s recent heated exchange is indeed a cause for commotion, but the 32-year-old may have a point on why Shaq is not really that fond of him.

O’Neal, a four-time NBA champion, has been called a variety of interesting nicknames throughout his decorated career. He has been referred to as “Diesel,” “Big Shamrock,” and “Shaqtus,” among other things, but “Superman” stands out among the many nicknames.

Howard may have a theory right there, but he himself could be a little insecure because of how the Hall of Fame center dissed him due to his “no-ring” credentials.

Howard will have another shot at the title this year as the Wizards aim to be a dark-horse contender in the Eastern Conference.
