Sixers minority owner Michael Rubin wants to play in his own sand box!

Rubin (middle above with Mehmet Oz and Julius Erving) is very interested in buying the NFL’s Carolina Panthers, sources have told told CNBC. The Panthers announced the team was for sale in December, after their longtime owner Jerry Richardson was accused of workplace misconduct.

Rubin has not yet put a bid in for the team, but is considered to be a very serious potential bidder.

“Nobody knows the NFL more than Michael,” one source told CNBC. Rubin declined to comment to CNBC.

Rubin has grown Fanatics into a $4.5 billion business, as one of the largest online retailers of licensed sportswear and merchandise.

At 45 years old, Rubin would be among the youngest owners in the NFL. He currently has a minority stake in the Sixers and the NHL’s New Jersey Devils.
