You’re talking about a “new” sheet - where was this mentioned previously? My understanding is that they turned in a sheet, which was the official sheet with designated starters and subs. Prior to kickoff, but after submission, they switched the players - new player can go on prior to kickoff without using a sub and the original player comes off and his game eligibility is expended for the night. There isn’t a new sheet that’s turned in other than the typical card handed to the Ref for the player coming on/one going off during a normal sub.
