O'Reilly is due a $7.5-million signing bonus that Buffalo would've been on the hook for as of midnight Sunday, but with the trade completed before that deadline, St. Louis will be picking up the hefty price tag.
Rumors had been percolating for the last few weeks regarding O'Reilly and a move away from the Sabres. After another season wallowing in the NHL's basement, the Sabres have pulled the trigger to offload O'Reilly's lucrative contract that carries another five seasons at a cap hit of $7.5 million.
O'Reilly is the biggest name in the deal but the Sabres did get back two veteran centers who will slot into their lineup immediately. As well, they acquire an intriguing prospect in Tage Thompson, who spent last season split between St. Louis and the club's AHL affiliate.
As for O'Reilly, the Blues are getting one of the best two-way pivots in the league. He had 24 goals and 37 assists in 81 games last season to go along with a 60 percent success rate in the faceoff dots.
