Waiver wire help

Solos 2, Assts 1, Big plays 3, TFL+1 and Ret Yds; 1 DL, 1DB, 1LB and 2 Flex

My Team:
DL - Cole
LB - Barnett, Poz, Mayo and Washington
DB - Burnett and Webb

Available:
Harper, Stewart, Pollard,Timmons, Harris, Levy

Concerned with
Webb - Are the last two games a trend or a blip? Should he be flipped for Harper, Stewart or Harper ROS?
Mayo - Does he come back fully in the next couple of weeks?

I see Harrison is back practicing and with the other Steeler inj's do we think Timmons will come back to last years form?

Thanks again! Your help is always appreciated.

I'd drop Webb for Harper (he still has to bye out however). I see no reason why Mayo wouldn't come back as the everydown linebacker in the next few weeks.

Timmons is an enigma. He's worth a stash in deeper leagues, but he's not startable until we see some signs of life.
