St. Louis Rams Rookie SUED — I Got You Tailor-Made Suits … and You Screwed Me!

St. Louis Rams rookie Robert Quinn was LOOKIN” SHARP after he was picked 14th overall at the 2011 NFL Draft … but now the guy who allegedly hooked up his fancy threads is suing … has learned.

No, we”re not talking about Quinn”s tailor … the dude with the beef is an agent who claims he repped Quinn during the draft … but was kicked to the curb right before Quinn signed his MASSIVE $9.4 million contract.

According to a new lawsuit obtained by … Carl Carey claims he signed a deal with Quinn when the former University of North Carolina defensive end decided to turn pro.

Carey claims Quinn was viewed by NFL teams as a guy with some serious “character flaws and health concerns” … until Carey reconstructed his image.

In the lawsuit, filed in federal court in North Carolina, Carey claims he did EVERYTHING for Quinn … including party-planning, media training, and even “arranging for tailor-made suits.”

Quinn also claims he negotiated deals with Nike and trading card companies.

But just before Quinn signed his contract … (months after the draft) … Carey claims he was fired … and has not received the 3% cut he was contractually obligated to receive.

Now, Carey wants payback … and though he hasn”t specified an amount … 3% of $9.4 mil is A LOT of money. Calls to Quinn have not been returned.
