With the NFL's version of summer vacation fast approaching, the Chicago Bears hold their final open OTA to the media before wrapping up the offseason program next week with a three-day mandatory minicamp.

Here is a list of storylines to monitor Wednesday at Halas Hall.

1. Tracy Porter: Porter's one-year deal makes sense on a variety of levels. Not only did the veteran cornerback play for head coach John Fox in Denver, he spent the beginning of his career in New Orleans where Bears general manager Ryan Pace worked for 14 years. After Kyle Fuller, and maybe Tim Jennings, the Bears have questions at cornerback. If Porter can stay healthy -- he appeared in just three games for the Washington Redskins in 2014 because of hamstring and shoulder injuries -- the 28-year old may be an option to consider at nickel back. Even if it ultimately doesn't work out for Porter in Chicago, there is zero risk in bringing in a player with 60 career starts and a Super Bowl ring on a one-year, prove-it kind of contract.

2. Offensive line leadership: Mentioned the other day how left guard Matt Slauson is taking on a more vocal role in the offensive line room in the aftermath of Roberto Garza's release. The same will be expected from two-time Pro Bowl right guard Kyle Long, who already has developed the reputation of being a strong team leader inside the locker room. It's exciting to imagine what Long is capable of achieving in the NFL, since by his own admission, Long spent his first two seasons in the league refining his game. Remember, Long is technically still learning. He only played a small amount of college football before the Bears drafted him in the first round in 2013, so it's not a stretch to imagine the best is yet to come.

3. Tight ends minus Bennett: Barring an unforeseen development, the final open OTA session will give media members the opportunity to watch the tight ends group perform without starter Martellus Bennett. The Bears are obviously a better football team with Bennett in the starting lineup, but the coaching staff is using the time Bennett stays away in a contract dispute to evaluate the other players on the roster. "They've done a good job," Bears head coach John Fox said of the tight ends. "I think there's a long list of them. But they've done a good job of learning the system both in the pass game and in the run game. I like what I have seen. There's some young guys there that, you know, some people may not have heard of. I think Bear [Pascoe] is probably the most veteran guy in that group. But they're working at it and they do a good job with it." The longer Bennett remains absent, the better feel the new group gets for Pascoe, Dante Rosario and Zach Miller.
