In Buccaneers QB Josh Freeman's fourth season and under his third offensive coordinator, he'll be asked to do and understand more than ever before. Whereas under former offensive coordinator Greg Olson's West Coast-based system Freeman would go through progressions then make his throws, Sullivan's system requires the quarterback and receivers to make critical pre-snap reads, then adjust routes accordingly.
That might not sound like much, but it adds another layer of responsibility that must be dealt with in mere seconds. Furthermore, being certain both parties are on the same page is essential.
"There are some things we do that (Freeman has) never been exposed to," coach Greg Schiano said. "And there are some things he used to do that we don't do."
It's going to be a process.
