Leading up to his unsuccessful bid to remain UFC lightweight champ this past weekend at UFC 144, former title-holder Frankie Edgar fielded countless questions surrounding the possibility of him dropping down to 145 pounds. After losing to Benson Henderson the level of speculation was amped up even further with Edgar responding to more queries about his weight than his actual performance against Henderson.

Though fans, media members, and even his employers may be pushing for Edgar to make the move to featherweight, at least one person with an intimate knowledge of the division thinks Edgar would be wise to reconsider.

Andre Pederneiras, who is divisional champion Jose Aldo’s primary coach at Nova Uniao, recently went on Twitter to warn Edgar about the risk of swimming in the pool with a shark like his star pupil.

“The biggest advantage that Edgar has he would lose at 66kg…his speed,” the widely respected trainer wrote before adding, “Aldo keeps the belt.”

Edgar himself has also been opposed to the idea of joining the featherweight roster, stating he wants an immediate rematch with Henderson based on how close their original encounter was not to mention how competitive he’s been in general at 155 pounds.
