CDL #1 had this in the rules:
“When drafting, state the player and price range. If a player is in the 9-10 million range, stating 9 million will suffice” - Midge
which...I like the “9-10” version better but I guess it makes sense. “9” is the same as “9-10” because anything in “9-10” starts with 9...so it’s kind of like saying 9,xxx,xxx.
