I believe so.
If the Defense can stop the run game and they had success against McCaffrey when they played in Carolina
Yes it's now a different O-line for CMC and he is running well, But the 49ers will have to beat the Browns D-line.
Purdy doesn't have the greatest long ball, He's a very accurate passer in the short to middle pass game.
The 49ers receivers are very good in YAC
The Browns need to tackle, tackle the legs and don't try to showboat by hitting high.
If the browns can pressure Purdy and take away the short to middle field, They can can keep the 49ers from putting up lots of points.
Walker has to do the same, get the ball off quick to the receivers and let them make YAC
This game I don't believe is going to be a blow out
There is a good chance the Browns defense can win this game
I'll start off Sunday with hopes of the Browns winning.
