Best Pick up

Our league just implemented IDP this year and going with just two flex IDPs.

My current two are

L. David
M. Kendricks

Any of these worth picking up?

Cushing
Laurenitis (just dropped)
Riley

Who's a better play this week and for the season?  I could drop an offense player to stash one of these.  Scoring is pretty skewed towards tackles

R. McClain DAL  is also available...seems to be doing well lately.

I'd continue to roll with David and Kendricks both have top 10 upside (David top 5).
