Allen, Branch and Berry on waivers

There's been a lot of panic drops this week. Should I chase on open waivers?

Solos 2, Assts 1, Tkl for loss +1, Most big plays 3, PD's 2; Play 1 DL, 1 LB, 1 DB, 2 flex

My team
DL = Cole
LBs = DQwell, David, McCarthy (trying to hold)
DBs = Chancellor, Pollard

Avail drops on waivers:
DL = Jared Allen, Hardy, Chandler Jones
DB = Branch, Berry, Peterson, Rolle

Avail free agents:
DL = Shaughnessy, Suh, Mincey
LB = Wright, Witherspoon, Riley, Sheppard, Kendricks
DB = K Coleman, Verner, Skrine, Jenkins, Landry

I'm concerned Cole wont get me the tackles. I doubt I can get Allen, but should I try? Is his start concerning? Branch?? Berry??

Thanks again.

I'd definitely pick up Allen and Branch. Not worried about Allen's slow start.
