Should i trade Chris Johnson for P. Manning on fantasy football?

You can't go wrong with Manning or Johnson but that's a tough one. I don't see Johnson with the exact same performance as last year but he will still be a monster. Peyton won't let you down and he'll be consistent every week. If you didn't have a good back-up I wouldn't do it but Flacco is gonna be good as well. Keep Johnson and make Flacco your starting back.
