Spencer Rattler named starting QB ; Jay Glazer reports Rattler expected to start next 3-4 games (month) until Carr’s return

Why would he announce this now and not wait until the last possible minute?

To be fair, it's not like there's any tape on what Rattler is going to do..with the makeshift OLine he'll at least be able to run. Bucs will still have no clue what were going to do with him or how we're going to use him.
