Is it best to just "practice" the new system while still playing the older system? or switch to the new system and just take the knocks for not being up to speed?  I took over at C. Washington in Rupp and they run a Press/Motion.  I want to move to Zone/Flex.  start playing zone/flex or continue playing motion/press since I have 7 players who were on the team last season (5 of which are seniors)

Few notes:

1) I don't know of any reason to switch from motion to flex. The offenses (sans FB) don't seem to vary much, if at all.
2) IQ's are key to success, so if you choose to change your O/D, I'd recommend playing the old system highly.
3) Good luck!

appreciate it!  thanks for the help!
