1. Chris Prosinski
Prosinski has spent the past two seasons in Chicago, but it could be the end of the line. Prosinski has mainly made his money on special teams but has made six starts in the past two seasons. However, this team has invested a lot in safety and if all things break well the numbers should push him out.
The first move they made was Quintin Demps who is likely to be a starter, and drafted Eddie Jackson who is currently hurt but has starter upside. Assuming Jackson will be healthy enough to play in 2017, he will make the roster. Adrian Amos, Harold Jones-Quartey, Deon Bush, and DeAndre Houston-Carson are all other options to make the roster, and given what is invested in all of these players, it is tough to say Prosinski deserves a spot over them.
Prosinski was a stud special teamer, but Jones-Quartey, Bush, and Houston-Carson can all play special teams. Sherrick McManis is another special teamer at cornerback. The team has mentioned moving Deiondre Hall to safety in training camp this offseason, which may mean them favoring McManis to Prosinski if keeping a special teamer. With so many names at safety it is very hard to see him sticking out in camp, and given the depth, they have on special teams, it becomes harder to make the case for the fringe roster player.
