One of the smaller needs that the Senators have going into this offseason is the need to figure out their 4th line centre position for many reasons: salary, roster spots, and opportunity. If the team is going to role with a similar lineup as they had down the stretch, featuring Kyle Turris, Mika Zibanejad, and Jean-Gabriel Pageau as the top three centres in terms of even-strength ice time, that leaves homegrown tough guy Zack Smith and last year's free agent signee, David Legwand, as the competitors for the final spot.
