Green Bay Packers vs San Francisco 49ers: 5 matchups to watch

3. Packers corners vs 49ers receivers

Against the Buffalo Bills offense, the Packers defense looked elite. However, you have to take into consideration the talent level they were playing against. They have the ability to look that good again this week. Wide receiver Marquise Goodwin has great speed, but he remains underutilized with Beathard under center. The young Packers corners have been dealing with injuries and growing pains as they adapt to the NFL.

Last week, Jaire Alexander missed the game, but Josh Jackson and Kevin King both were up and down. They each have the size and athleticism to be great at this level, but they can be taken advantage of on good routes. A coach like Kyle Shanahan can scheme his receivers open, and he can make life difficult on these young corners. If the 49ers start small with Goodwin, the big play down the field could be available.

Alexander should play this week, which Packer fans will enjoy seeing because of the potential he has flashed thus far. He should draw Pierre Garçon in the slot, which means bad news for Garçon. Alexander has been a top-20 cornerback thus far, and he continues to trend upward. If Alexander wins his battle, it will come down to the outside guys. They need to focus on preventing big plays because those ate them alive last week.
