Trade winds continue to blow during a swap-heavy offseason in the NFL.
A fourth-round pick of the Ravens in 2012, Gradkowski needs polishing. He was a problem for Baltimore in 2013, ranking dead last among the league's 35 qualifying centers, per Pro Football Focus. Game tape showed far too many breakdowns, but the hope is that Gradkowski will develop for a Broncos squad undergoing a facelift up front.
With new Broncos coach Gary Kubiak set to implement his zone-blocking scheme, it's possible he saw positive traits from Gradkowski during his tenure as Baltimore's offensive coordinator. With Manny Ramirez finishing last season at right guard and Will Montgomery unsigned, the untested Matt Paradis is the only other center on Denver's roster.
