"When the Toronto Blue Jays couldn’t come up with the money to sign Ervin Santana last month, Edwin Encarnacion, Jose Reyes, Jose Bautista, Mark Buehrle and R.A. Dickey stepped up deliver the cash, multiple sources told Sportsnet on Friday."
Shi Davidi knows his stuff and said exactly that in the Blue Jays did not have the money to sign him so the players offered to defer salary. Also it was approved by the MLBPA, so there is that.
Bottom line, if a club has money to spend they are not going to get players to defer their salary to sign a player. What evidence has there been to suggest the Blue Jays have money to spend?
