Head coach Kyle Shanahan and the San Francisco 49ers are currently in the middle of what will be a very important offseason for the direction of the franchise. The 49ers are coming off a devastating overtime loss to the Kansas City Chiefs in last month’s Super Bowl 58 in Las Vegas, and Shanahan is now looking for ways to make the rival team even better. Greenlaw suffered an Achilles injury while jogging down the sideline to. the court between sets. With Greenlaw out of the lineup for the foreseeable future due to a nagging injury, the 49ers could have another quarterback this offseason.
