1o Bears are slated to become free agents — both unrestricted and restricted — when free agency officially begins on Friday. Below: who, and the likelihood they’ll return to the team.

Unrestricted

Adewale Ogunleye, DE

You could argue that Ogunleye never lived up to the high expectations that followed him once the Bears gave Marty Booker and a third-round pick to Miami for his services in 2004. Then, again, you could argue that Alex Brown is no Jason Taylor. With the unfortunate passing of Gaines Adams and Mark Anderson’s return all but imminent, you might expect re-signing O-Gun to be a no-brainer. Not so. Most, including Ogunleye, expect him to play elsewhere in 2010.

Chance of return: Doubtful.

Adrian Peterson, RB

I was first told about Adrian Peterson when he was tearing it up at Georgia Southern. My brother-in-law went to school there and had mentioned before the draft that this kid, was in fact, a stud. When the Bears drafted him, I was intrigued. While our AP never translated his collegiate success to the NFL, he’s been effective when given the opportunity and is an above average special teamer. Last year’s late emergence of Kahlil Bell and the Bears likely pursuit of a running back in free agency lowers the likelihood he’ll be back.

Chance of return: Questionable.

Pisa Tinoisamoa, LB

Suffering a season-ending injury in Week 1 the season prior can significantly damper your list of suitors the following offseason. The Bears will bank on this. Expect Tinoisamoa to be offered, an accept, a one-year, incentive-laden deal. After all, Urlacher-Briggs-Tino can still be promising.

Chance of return: Probable.

Darrell McClover, LB

McClover has found himself on and, then, off the Bears roster a lot since 2006. Being off once more won’t phase him. Depending on how they handle their restricteds, the Bears are good in linebacker depth and Timmy Shaw is already the new Brendan Ayenbadejo.

Chance of return: Doubtful.

Restricted

The Chicago Tribune breaks down tenders and restricted free agency quite nicely.

Mark Anderson, DE

I honestly don’t know what to make of Mark Anderson. Since his 12-sack rookie season in 2006, he’s been practically invisible. He amassed 3 1/2 sacks last season under Rod Marinelli’s direction when Marinelli was supposedly the one man who could get the most out of him. Clearly, that didn’t work. Anderson is best as a situational pass-rusher and unlikely to be paid like a full-time starter. On the other hand, if the Bears lose both him and Ogunleye and fail to sign a free agent defensive end, they’re suddenly left very thin at an important position in their cover-2 defense. I have a feeling the Bears slap a second-round tender on him, if not just for that.

Chance of return: Probable.

Danieal Manning, S/KR

It’s already been made pretty clear that Manning will get a shot at strong safety in 2010. Plus, he has value as a return specialist.

Chance of return: Will return.

Nick Roach, LB

Roach came in last year and played admirably in Tino’s absence. He and the oft-unused Jamar Williams are both talented enough to start somewhere, so why would they stick around unless given the chance to compete at strong outside linebacker? They won’t. Don’t forget Hunter Hillenmeyer is still hanging around, too. Based on the way in which the Bears have distributed playing time in the past, my gut feeling is that Roach gets a second-round tender. Worst case scenario: An other team takes the bate; Bears fail to match, receive second-round pick and turn attention to Williams.

Chance of return: Probable.

Jamar Williams, LB

When Jamar Williams was drafted, it was expected that he would be groomed as the replacement for a departing Lance Briggs. Well, Briggs never departed and Williams has yet to get a fair shot. The Bears could try to tender both he and Roach for insurance purposes, but I can’t envision a scenario where both are brought back. More likely to happen is the Bears let Williams walk.

Chance of return: Doubtful.

Josh Bullocks, S

Eh … Bullocks might receive a low-level tender simply because the Bears are so desperate to retain any potential talent at a weak position. Then again, probably not.

Chance of return: Doubtful.

Dusty Dvoracek, DT

Is dude still on the team? I could have sworn he was let go already because of his sub-par ability/injury-riddled body/penchant for beating up people in Oklahoma bars.

Chance of return: Will not return.

==========

Of course, this is all wild, wild speculation, but if you’re keeping score at home, I’ve got Pisa Tinoisamoa, Mark Anderson, Danieal Manning and Nick Roach as coming back. Adrian Peterson is a toss-up. Everybody else is gone.
