I think I fouled up by picking a team with the FB "O" as my first ever HD team, so I started to train in Flex since I've only got 2 Frosh and then will run the FLEX next year (this plan was with the help of a mentor from the boards).

I just got an email from my #2 stating:

Coach, I've heard some grumblings and I'm sure you have a reason we just don't see yet, but why do you have us play fastbreak in our games when we don't practice it?

Is this something I need to worry and fret about? OR is it just an automated reminder for those who may accidentally jack up their coaching settings?  Should I commit 1 minute to the FB to appease the masses?

It's an automated reminder.

just ignore it the message. if you are going to switch, put 20-25 minutes into flex and 0 into fastbreak. the transition period may be tough, and you might need to sweat it out a season. but it will be worth it later.

I figured as much, but assumptions are the mother of all fork-ups.
