If Tampa Bay fails to make the Stanley Cup Playoffs in 2015 and get the first pick in the draft, Philadelphia will receive the New York Rangers' 2015 first-round pick, acquired last season as part of the Martin St. Louis trade, in lieu of Tampa Bay's first-round selection.
Coburn has one goal and eight assists in 39 games this season. He has one more season remaining on the four-year contract he signed in November 2011.
"I'm excited to go to Tampa Bay," Coburn said on TSN. "They've got a great team. Little sad to leave Philly but I'm looking forward to getting down to Tampa."
