Just done a quick CTRL+F of the Trade Tracker to see how many times some oft-traded names were moved.
Brady Stropko - 6 Times (SEA to QUE, QUE to HSK, TOR to CGY, COL to STO, STO to DAV, DAV to COL)
Tyson Stokes - 5 Times (HSK to TOR, TOR to STO, STO to QUE, QUE to NYA, NYA to COL)
Edwin Encarnacion - 5 Times (RIG to SEA, SEA to COL, COL to CGY, CGY to QUE, STO to CGY) *Last two were FA rights.
David Hamilton - 5 Times (TOR to COL, COL to NYA, NYA to STO, STO to CGY, CGY to RIG)
Francis York Morgan - 5 Times (STO to QUE, QUE to CGY, CGY to TOR, TOR to NYA, NYA to DAV)
Azmet Ali - 5 Times (DAV to QUE, QUE to COL, COL to DAV, DAV to COL, COL to NYA)
Those aren't necessarily the most traded guys, I was just CTRL+Fing guys who I remembered being traded quite a bit.
