Rappaport tweeted: "#Lions plan to start renegotiation talks when he hires an agent" in response to a Detroit columnist writing that Suh could be traded.
Although it would be fairly beneficial for the Lions to trade Suh, they could get picks to address holes in other areas of their defense and save money in the process, the 4th year player has proven himself to be a great pass-rusher and was voted into the pro-bowl last year.
Suh was also voted a team captain by members of the Lions team last season.
The former Batlimore Ravens offensive coordinator, Jim Caldwell will take over as head coach of the Lions this year after the firing of Jim Schwartz and the end of last season.
Detroit have a history of devoting lots of cap space to big stars such as Matthew Stafford, Calvin Johnson and Suh but will try to limit their spending elsewhere in the roster to develop a balance.
The Lions have not made the playoffs since 2011. They finished last season with a 7-9 record despite leading the division for a large part of the season.
