Perry Riley Fever?

I sat Navorro Bowman last week because I thought he was too banged up.
Definitely won't make that mistake again this week.

So I have one more spot for an LB.
I have Lofton vs Tennessee

or

I could pick up Perry Riley who is an undiscovered gem against what is sure to be a Demarco Murray heavy Cowboy offense.



It's 2 pts per tackle, 1 pt per solo

So should I pick up Riley or just stick with Lofton?

The player I'd drop would be just excess baggage.

Thanks in advance for any advice!
