Who are best UDFAs in Bears history?

I know the Bears didn’t draft a quarterback and I’m pretty sure they didn’t sign an undrafted free agent. So who played quarterback at the rookie minicamp?

The Bears had two quarterbacks at their rookie minicamp: Ryan Willis, who was one of four first-year pros; and Drew Plitt, who was among 36 undrafted rookies participating on a tryout basis. Willis was signed to the Bears practice squad last Dec. 18 and flexed to the active roster to back up Nick Foles in a Week 16 win in Seattle. Willis then signed a reserve/future contract with the Bears Jan. 11. Plitt played the last five seasons at Ball State, passing for 9,061 yards and 68 touchdowns.

How many punters have the Bears drafted? It seems to me like it’s a rare occurrence.

Since the NFL Draft was reduced to seven rounds in 1994, the Bears have now selected three punters: Todd Sauerbrun in the second round in 1995, Pat O’Donnell in the sixth round in 2014 and Trenton Gill in the seventh round this year. The only other punter the Bears have drafted since 1987 was Chris Gardocki in the third round in 1991.
