Brandon Jacobs, Julio Jones, or Mike Tolbert in flex?

[idrive300]

Hello! I am new to the forum and this is my first season as an owner. I am having trouble with picking my flex player in week 1.

Brandon Jacobs vs Wash
Mike Tolbert vs Min
Julio Jones vs Chi

I like Jacobs because he san run very well against the Redskins lately. Tolbery should get a good amount of touches in the red zone. Jones has me perplexed because he is a rookie but the Chicago secondary might be loose.

Any thoughts?? Thank you!
