KTVU's Joe Fonzi sits down with 49ers head coach Kyle Shanahan

The 49ers haven't had a winning season since 2013 and they're opening up the 2017 with first-year head coach Kyle Shanahan -- the organization’s fourth head coach in as many years. 

Shanahan views quarterback Brian Hoyer as a player who has gone through adversity and recognizes such a process as one that often either makes or breaks a player. Shanahan believes it has made Hoyer a stronger, more developed quarterback.

As for the defense, who was ranked dead last when the 2016 concluded, Shanahan is confident with the off season acquisition, Robert Saleh. The two have experience coaching together (2006-2009, Houston Texans) and Shanahan has done well to remind him of the reality of the situation he was hired into.

"When you're 32nd it's hard to get worse," Shanahan said, when discussing his approach to defense with Saleh. "Our expectations are to get better."
