FAAB Spending w/ other team budget breakdowns

Hello everyone!

I have a more in depth question about how much FAAB I should spend for some free agency pickups and if these players are worth the add. I am the 5 seed in an 8 team playoff in a 12 team full point PPR league.

I am trying to lay claim to Alex Smith and Mike Davis in a full point PPR league with a budget of $70 (out of $150) remaining. My current roster is as follows:

QB: Matt Ryan, Keenum
RB: McKinnon, Perine, Ajayi
WR: Hopkins, Evans, Gordon, Marvin Jones, DeVante Parker, Kupp
TE: Olsen, Julius Thomas
DEF: Ravens, Patriots
K: Forbath

The reaming budgets of the playoff teams are as follows: $6 (my current opponent), $11, $149, $75, $24, $14, $40.

The $149 is the current #1 seed but since he has Brady I’m not worried about him going after Smith (he’s a Pats fan).

How much do you feel I should put on each player? I’m currently dropping Keenum for Smith and Parker for Davis.
