Tkachuk brothers drive Panthers' renewed motivation

Brady Tkachuk is training with Panthers teammates in Fort Lauderdale and says joining Florida is about competing for a championship, not simply playing with Matthew. Matthew remains frustrated by last season's playoff absence and is entering camp with renewed motivation, while the brothers' integration and Florida's optimism are major preseason themes; Brady's Oct. 21 return to Ottawa remains an emotional storyline. No contract development or roster change has emerged.
