Sanzenbacher appeared in just four games for the Bears in 2012, hauling in just one reception for seven yards. As a rookie in 2011, Sanzenbacher appeared in 16 games, recording 27 receptions on 54 targets, for 276 yards and three touchdowns.
Unfortunately for Sanzenbacher, the Bears opted to relieve Mike Martz of his duties as offensive coordinator, and instead installed Mike Tice. Martz' offense emphasized a slot receiver, while Tice's offense does not. Further, the Bears brought in a handful of receivers this past offseason, including Brandon Marshall and Alshon Jeffery -- moves that helped diminish Sanzenbacher's role.
Sanzenbacher was signed as an undrafted free agent out of Ohio State University in July 2011. As a senior in 2010, Sanzenbacher caught 55 passes for 948 yards and 11 touchdowns.
