Any tips? I got 770k
Yeah get some linebackers :) I assume you run a lot of dime based on your lineup. You can get Kerby Joseph for free from the weekly wildcards BND pack in the competitive field pass. Bozeman as a free center upgrade from the team affinity solo challenges. Apart from that I would wait a little bit for the Free Agency prices to drop and go for one of the 98s. Maybe Tomlinson, in your case.
My guess is you're running Dollar or Nickel formations and subbing in safeties at LB, so LBs aren't a priority. If it's working, no reason to switch it up.
Without knowing the schemes you're running it's hard to make precise suggestions. If you're running man, you can pick up Marcus Peters for free later today. He might not jump out at you looking at the ratings, but he's the first player that can get Inside Shade for 1 AP.
On offense, I'd probably upgrade from Biletnikoff. Maybe look at someone like Tyreek Hill. 0 AP Short In Elite with 1 AP Grab N' Go which gives you perfect pass leads when targeting him. He also has 99 SPD stock along with 98 ACC, 98 AGI, and 99 COD. He's great in the slot, but there are a ton of solid and affordable options for a slot WR if you're not feeling Tyreek.
