You have a lot of bracketologists to choose from, but Joe Lunardi, Lucas Harkins, and Brad Evans consistently prove to be the most accurate. They have their own bracketology sections on ESPN, Heat Check CBB, and Yahoo! Sports respectively where they present updated predictions and statistics.  Public networks might block the NCAA bracket and stop you from updating your choices. This could be bracket-breaking if you can’t change your predictions last minute. Luckily, a VPN service can quickly unlock your bracket, saving you unnecessary stress.
