Super Bowl Help for Friend

[NYG1119]

My friend is probably gonna lose to a ridiculous team who has won 9 in a row from 1-4.

14-Team PPR

His team
QB: Stafford
RB1: Morris
RB2: J.Bell
WR1: Marhsall
WR2: M. Williams
TE1: Scheffler
FLEX: M. Owens
D/ST: Raiders
K: Novak

Bench
RB: Bradshaw*
WR: Streater, Little
TE: Vernon Davis
D/ST: Ravens
K: Crosby

So what you guys think. Is Davis worth a FLEX even though he hasn't done anything in the last 3 weeks. For Defense, Browns and Rams are on the WW, should he grab anyone of them.
