Time to quit on Quin?

Sorry to bring this up again Mr. Guru, Sir, but I'm wavering again on Quin.  Here's the recap of my situation:

ESPN leagues have Glover Quin tagged as a CB, but he's currently a SS.
(sorry for the lame question here, but the Strong Safety doesnt have as many tackle opportunities as a Free Safety, right?)

Is it time to cut losses on Quin, or should I try to keep the faith for another week?

I lost out on Brandon Flowers, but Tim Jennings and Eric Wright are still available (as are Revis and Greer).

My other CB is Arenas...it's a Return Yardage League (1 pt. for every 10 yards returned).

Tackles are 1 pt
Asssists .5 pts
PD are 1 pt.

Thanks for any help!

SS tend to get more tackles, since they are often the 8th man in the box in run support.

I think it's time to cut bait with Quin. I like Jennings. I would pick him up.
