playoff push and playoffs themselves

[Silence]

my league has the following settings. 4 throwing tds, 6 pts running and recieving. milestone scoring 3pts for 100 and 5pts for 200 reciving and rushing yards. milestones for 300 (3) and 400 (5) yards passing also. starting 1 qb, 3 wrs, 2 rbs, 1 w/r, 1 te, 1 K, and 1 def.

Is this good enough to make the push with? do you see any changes I should make? I'm somewhat worried about my flex spot, at what point do i cash in depth for a good flex spot starter?

Thanks for the help
my roster is the following:

QB drew Brews
WR A johnson, jennings, maclin
BN julio jones, nate washington, ward
RB foster, forte
BN tolbert, tate
TE graham
BN shockey (just incase injury pick up for graham this week. )
K gould (chi)
DEF Baltimore
