ALLEN PARK -- As long as there are talks there is progress. That’s Lions president Tom Lewand’s take on the negotiations with defensive tackle Ndamukong Suh, the second overall pick in the draft.

“We’ll keep diligently working at it until we have a deal done,’’ Lewand said as training camp got under way today (Saturday).

Suh is the only first-round pick who has not been signed. It was thought that once top pick Sam Bradford was signed by St. Louis, it would be easier to fit Suh into the slot behind him

“The more reference points we have the more helpful it becomes, but at the same time every deal is unique, every deal is its own deal. The only thing we can do is continue to work hard to get a fair deal done for Ndamukong Suh and our club,’’ Lewand said.
