In what I consider to be an 'avoid waiver issues' move, Mathieu Perreault was recalled by the Capitals while Keith Aucoin was reassigned to Hershey.
If Aucoin were to spend 10 games or 30 days straight with the Caps he would have to clear waivers if they wanted to send him back to Hershey. This way they keep that from happening.
Honestly they are very similar players. Both are small playmaking centers. Aucoin is more experienced and can do more scoring but Perry can do amazing things with the puck on his stick and is probably the faster skater right now.
Congrats to Perry for getting his chance and to Coiner...you will surely be back up there soon.
