Help me IDP Guru, you're my only hope

I ran out of money in our auction draft and got somewhat squeezed out in my IDP players. I'm also new to IDP so I'm not quite sure what I'm doing :D We have a pretty simple league and only have to start one each of DL, LB, DB. Scoring is the same as you use except 2 points for interception and 1.5 for half a sack.

DL - I didn't draft one and these are available:
Frank Clark
Akiem Hicks
Carlos Dunlap
Cameron Heyward
Everson Griffen
Clowney
and pretty much everyone else except the big names.

LB - have CJ Mosley, available are:
Blake Martinez
Myles Jack
Christian Kirksey
Devin White

DB - I have Johnathan Abram, available are:
Harrison Smith
Antoine Bethea
Malcolm Jenkins
Jessie Bates

Would any of the LB/DB be a significant upgrade over who I already have? As of now I have a bid in for Frank Clark for my DL.

Thanks, this site looks like a great resource!

I'd bid on Clark, stay put at LB, and put in for Harrison Smith over Abram. I like Abram but Raiders play two high safeties a lot, so he may not play towards the line of scrimmage as much as people think. Smith is solid year in and year out.

That was quick! Thanks, that helps a lot, I'll put in a bid for H. Smith but I think I'll hold on to Abram for a week or two just to see if he pans out.
