Browns' Defense Shines in Upset Win over 49ers

San Francisco 49ers head coach Kyle Shanahan expressed disappointment in the team's defensive performance against the Cleveland Browns' run game, citing missed tackles and the inability to stop the run as key issues. Shanahan mentioned playing a lot of Cover-2 defense and suggested that the defense should have sold out on the run more, especially with a quarterback making his first start. Defensive coordinator Steve Wilks may need to make more proactive adjustments going forward, and the absence of Dre Greenlaw on Sunday made things more challenging.
