Before anyone gets too excited about the possibility of free-agent linebacker LaVar Arrington joining the Green Bay Packers, consider the variables at play. Arrington wants to play for a winner; the Packers were 4-12 last season. Arrington wants to know whether Brett Favre is going to retire; the Packers still don't know the quarterback's plans. Arrington wants a big contract; the Packers have plenty of salary cap room but don't think they should have to pay considerably more than what the market bears.
