(Renton, WA)  --  "Beast Mode" may not be around when the Seattle Seahawks' minicamp starts next week.  Yahoo Sports quotes sources as saying running back Marshawn Lynch is expected to miss at least part of minicamp.  ESPN is reporting that Lynch is unhappy with his contract and is looking for a new one that pays more than his current five-million-dollar-per-year base salary.  Lynch skipped the Super Bowl champions' visit to the White House last month and hasn't participated in any of the Seahawks' voluntary organized team activities.
