Bizarre shakeup at the top in Carolina

Posted by ESPN.com’s Pat Yasinskas

Bizarre story out of Carolina on Tuesday. David Scott and Charles Chandler report that Mark Richardson has resigned as the Panthers president and brother Jon Richardson has resigned as stadium president.

The Panthers aren’t giving any explanation yet and this one seems really strange because the Richardson brothers essentially have been running things the last few years -- even before father and team owner Jerry Richardson underwent a heart transplant in February.

The Richardson brothers will remain part of the franchise ownership group, but this one smacks of some sort of internal conflict. Mark Richardson has been influential in league circles and is a member of the competition committee -- although we’ll see if this changes that. Jerry Richardson still is recovering from his surgery and has resumed some duties. The Panthers have been run almost entirely by the Richardson family since they came into existence and it’s hard to imagine that changing.

I’ll check around and see if I can get more details on what’s behind this very strange move.
