Robert Griffin III is most often called RGIII. If you ask Giants defensive end Osi Umenyiora, however, he hasn’t earned the nickname yet.

From the New York Post, who transcribed Umenyiora’s interview with WFAN 660:

Of course, Umenyiora from time to time doesn’t mind some stick-poking. He shows respect for opponents but refuses to heap praise on players who haven’t proven anything. Case in point: He will not refer to Redskins rookie quarterback Robert Griffin III as RG3 even though that’s basically what everyone calls him.

“Who is this RG3 guy you guys keep talking about?’’ Umenyiora said. “You talking about Bob Griffin? You guys are giving him a cool nickname already and everything. When he does anything in the NFL we’re gonna call him RG3. Right now he’s Bob Griffin.’’

Something tells me Bob won't be too concerned with what Umenyiora calls him. Perhaps Osi would prefer Heisman Trophy winner Robert Griffin III.
