Okay, I think I got this figured out, for others who may be having problems getting the Field Pass objectives completed that launched today (Thursday 6/29/23).
There are two North Division releases today (AFC + NFC). Each Division has 4 teams (eventually that will be 32 teams, I'm assuming it's the first pick in this past draft for each team).
It takes 2 X 98 Heroes to complete one of the EIGHT Rookie Premiere players that dropped today (again -- AFC/NFC North, eight players). I did a few of the non 99 OVR Sets to satisfy the Field Pass sets objectives and ended up with multiple 98 OVR Heroes (Dorance Armstrong RE for example). If you plug those two 98s into one of the eight 99 OVR RP sets, not including the Steve Smith Redzone Royale set, or the Kyle Hamilton Redzone Royale set) , you will get one of the eight rookies that are required to complete the Field Pass objectives.... The OP mentyioned Zay Flowers,the player that I found in the eight AFC/NFC North 99's that dropped today...
I'm assuming if you get the Zay Flowers and put him on your team and start cranking out yards, tackles, points and Solo Battle wins, the FP objectives will start being met....
Sigh, I hate to use my 2 x 98 Heroes to get a player I don't actually want or need, I'd wait until the NFC East and get the Cowboys player, but I also hate going a few weeks letting all these stats I'm wracking up go to waste.
FYI: if you're looking for specific positions, here are the rookies that dropped today by position: Darnell Wright RT, Lukas Van Ness LOLB, Jahmyr Gibbs HB, Jay Ward FS, Dawand Jones RT, Darnelll Washington TE, Zay Flowers WR (mentioned in OPs message) and DJ Turner CB.
All are 99 OVR Golds, all are from AFC or NFC North Teams, and (big assumption) hopefully they satisfy the Field Pass objectives that showed up today....
