Calgary could be losing a key cog in its OL to free agency.

It’s not often one of the CFL’s top players hits free agency in his prime. Yet Stamps offensive lineman Derek Dennis truly is one of the league’s best and, at age 28, the Stamps’ left tackle could be about to go on the market.
The mammoth 6-foot-3, 341-pound lineman helped Calgary surrender a league-low 20 sacks throughout 2016, also paving the way for CFL leading rusher Jerome Messam (1,198 yards).
And while Most Outstanding Player Bo Levi Mitchell had a season to remember and the Stamps’ defence also rose to the occasion throughout the year, much of the credit for Calgary’s historic 15-2-1 record belongs to the offensive line.
It was Dennis, the second-year Stampeder, protecting Mitchell’s blind side the entire way, allowing the Stamps’ pivot to stand mostly unscathed while throwing for 5,385 passing yards and a league-best 32 touchdowns.
Dennis is the sixth-ranked player pending free agency according to CFL.ca’s Top 30 Pending Free Agents:
