Adding a UDFA stage to the Draft
I think adding a fleshed out Undrafted Free Agent stage post draft would not only make the game more accurate, but also give opportunities to sign more depth players or possible stars.
Currently the undrafted players hit normal free agency but the decent players are signed by the CPU teams immediately and the rest are ~50 OVR.
But a system like the current FA system with bidding and motivations with the player's ovr hidden like players during the draft would be very interesting and I'd personally love to dabble in the UDFA market.
I don't know if the idea would be popular but for players like myself who enjoy playing the game like real NFL football, which I believe 23 has come the closest to, I think they'd enjoy having a quick 1 stage UDFA week to add some young depth players without using up late round picks
