Heading into this offseason, the Denver Broncos are expected to be one of the most active teams in the league looking to upgrade at the quarterback position. This has become their clear plan of action as free agency period has inched closer, now just a couple of weeks away, and the Minnesota Vikings’ Case Keenum could be in play. This year’s crop could include a few intriguing options being available on the open market that could step in immediately to help turn things around in Denver. According to Troy Renck of Denver7 ABC, Broncos could be a potential landing spot for Keenum in free agency with Minnesota expected to let him walk.
