LB help week 10

Lots of good options at linebacker.  Who would you pick up out of this group.

Shazier(PIT)/Craig Robertson(NO)/Nick Bellore(SF)/McKinney(HOU)/Alexander(BUF)

My current roster for IDP - we play 4 per week
Donta Hightower(NE)
Avery Williams (TEN)
Jerrell Freeman (CHI)
Kiko Alonso (MIA)
Nigel Bradham(PHI)

id rank them

Robertson (only everydown healthy LB Saints have)
Mckinney
Shazier (Talented but made of glass)
Alexander (Sack machine)
Bellore (SF seems to have a weird rotation)

my opinion

i have ZBrown, Whitehead and MSmith on bye
JBrown and EKendricks (out/questionable

so at flex will have to roll either BMarshall or EKendricks if he plays
