Payton/Saints may have not re-signed Brees to the 2 year deal in 2018 if Mahomes was drafted here. I’m not sure Payton would wait 3 seasons to let Mahomes take over while he thought of him as the greatest prospect ever. Brees’ contract was expiring at the perfect time to roll with Mahomes in 2018 and start the SB run he’s been on since then.
