DB Question

I'm in a 12-team dynasty PPR, IDP league. Tackles and passes defensed are worth 1.5 pts and assists are .5 points. Sacks, forced fumbles and fumble recoveries are worth 3 points. INTs are worth 5 points.

Which of these 2 corner backs would you start:

Cason vs. ARI
Vontae Davis vs. NE
Tracy Porter vs. CAR
Glover @ OAK
Thurmond @ STL
A. Verner vs. DEN

Also, I need to drop two players. Who of these players would you drop (including the CBs listed above):

DeCoud
Sean Jones
Brad Jones
Jalen Parmele

Thanks again for your help guru!

I'd go with V. Davis since he's reportedly going to be shadowing Moss all game and should see a lot of tackle opportunities. And I like Verner this week as Orton will likely look his way a lot.

I'd probably drop:

Brad Jones
Jalen Parmele

Thanks for the input guru, much appreciated. And by the way, your rants are hilarious. Glad to see that you rank the 2nd Ace Ventura movie above the first.
