Randy Wittman acknowledged it's going to be an important offseason for Kevin Seraphin, Trevor Booker, Chris Singleton and Jan Vesely. All four reserves regressed this season and it was pretty obvious to see. "It's time for them to step up and show me who we need to move forward with and who we don't," WIttman said. Seraphin and Booker have shown some promise throughout their young careers at certain points, but Singleton and Vesely have been largely disappointing since being drafted in the first round of the 2011 draft.
