The Cardinals’ first move of free agency was to strengthen what had already been one of their best units. The Arizona secondary got a boost in the opening hour of the new league year with the addition of one of the league’s most underrated safeties, Tyvon Branch. Branch entered the league as a fourth-round pick of the Oakland Raiders in 2008, contributing immediately as a rotation player and taking on a starting spot in 2009. He spent seven years with the Raiders, where he was considered so important to the team that they placed the franchise tag on him in 2012, leading to him signing a four-year contract there. This article from ProFootballFocus breaks down exactly how Branch shut down Rob Gronkowski, highlighting exactly what Branch can bring to the table. Unfortunately, Branch has suffered with injuries throughout his career, and he played only five games over the 2013 and 2014 seasons for the Raiders, who subsequently released him. Branch got his career back on track last year in Kansas City, playing in all sixteen games for them in 2015 and helping them go on an 11-game win streak including their first playoff victory since Joe Montana was the team’s QB, though Branch was a rotation player rather than a starter. He now joins one of the league’s most exciting young secondaries in Arizona, highlighted of course by Patrick Peterson and Tyrann Mathieu. Branch will be an immediate contributor to a Cardinals side that fell just shy of reaching the Super Bowl last season.
