When looking at the Cardinals’ needs heading into the offseason, many people place left tackle right at the top of the list. Bradley Sowell finished the year with a strong stretch of play as he allowed no sacks in the final four games. He allowed seven sacks up to that point and graded out at the bottom of the list of the league’s left tackles according to Pro Football Focus, but that’s not leaving coach Bruce Arians feeling desperate for a new option at the position. While he said it is a spot the team will look into upgrading, Arians said it isn’t the first place they’re looking to improve. “Bradley played OK, and he’s going to get better with another year of strength and conditioning,” Arians said, via Josh Weinfuss of ESPN.com. “It’s not the most glaring need.” Arians didn’t identify the most glaring need on the roster, but the offensive line in general has to be near the top of the list. With 2013 first-round pick Jonathan Cooper returning from a broken leg and right tackle Eric Winston heading for free agency, the Cardinals won’t lack for options about how to address those needs.
