Few days in Flyers history have ever been busier than today, with several high profile trades altering the franchise in the last decade alone.
For starters the Jeff Carter and Mike Richards trades were executed on June 23rd of 2011, as was the ill-fated James van Riemsdyk trade (for Luke Schenn) a year later, the Scott Hartnell for R.J. Umberger swap two years later, and finally the Brayden Schenn trade three years later (for two first-round picks and Jori Lehtera).
Those are some massive trades and ironic that they all occurred on the same day though years apart.
