On the field: The Bears have been in need of a pass-catching tight end since trading Greg Olsen last summer. Rodriguez is that, but the team hopes he also can block linebackers, seal the edge in the running game and be a vertical threat.

Upside: Rodriguez has lot of offense to learn, but if he can, he could be a three-down player and provide a boost in all phases. He's a purer receiver than Kellen Davis and will add a dynamic that didn't exist under Mike Martz.

Downside: Rodriguez is undersized and isn't physically imposing, which will make him iffy as a blocker in the running game. He also comes with off-the-field baggage, but the Bears hope those issues are behind him.

Most resembles: He likes to compare himself to the Patriots' Aaron Hernandez, who is about the same size and has similar speed. The Bears will be giddy if he can find similar success.
