Martellus Bennett is a very good tight end. There’s no doubt he’s an upgrade over Kellen Davis and the past mediocre options the Bears have trotted out there. Bennett gives the team skill and stability but what’s after him is little to be desiered.
There are two tight ends named Zach Miller in the NFL. One has over 300 career receptions and a Pro Bowl honor and the other plays for the Bears. The Miller the Bears have had back to back seasons of at least 20 receptions when he first came into the league back in 2009 but has managed to catch only four passes since. He’s still likely the team’s second tight end.
Rosario certainly knows the offense after spending a season with the Bears last year but he had only one catch in 2013. He will fight for a roster spot but very well could be beaten out buy a more athletic player.
Mulligan is the most intriguing option. He’s spent some time with the Patriots, Rams and Jets. He has lined up in the slot and has been a very solid blocking tight end. His athleticism and versatility could be a help on special teams and might just knock Rosario off the final roster.
Mastrud is a long shot to make this team. He has made a career of bouncing around from camp to camp trying to find a spot on a roster. He was once a key target of Josh Freeman back in their Kansas St. days but has since struggled to stay with a team.
