CINCINNATI -- The first time ESPN NFL draft analyst Todd McShay filled out a mock for this year's class, he sent offensive tackle Andrus Peat to the Cincinnati Bengals with the 21st overall pick.

Now, about a month from the first night of the seven-round draft, McShay has come full circle. For the first time since December, he has the Bengals picking Peat and shoring up their depth at tackle.

In the two mocks between McShay's first and his most recent, published Monday morning, he had the Bengals thinking pass-rush with their first-round selection. He wasn't the only one. After all, the Bengals needed help in that area after amassing just 20 sacks last season. Mind you, those two mocks came before the Bengals signed free-agent defensive end Michael Johnson for a second stint with the club earlier this month.

Along with Johnson, the Bengals made two other defensive-line moves since McShay's previous mock, re-signing defensive tackle Devon Still and adding Pat Sims for his second tour in Cincinnati.

Needless to say, the defensive line most likely won't be the Bengals' most pressing draft need now.

Which means it makes sense McShay is thinking offensive line with this pick. It's the same thought I've had for a while myself, especially the more likely it seemed the Bengals might be able to make at least one addition to their defensive line via free agency.

If you've been following along, you know that my O-line pick for the Bengals has been LSU product La'el Collins. Not only did he impress at the combine -- running a 5.12-second 40-yard dash that was the sixth-best among all offensive linemen -- but he has a measure of versatility that matches perfectly what the Bengals seek out of blockers. He can play both guard and tackle.

Collins also has that LSU pedigree the Bengals seem to like. Relationships with coaches at the SEC school convinced them to take the gamble on Jeremy Hill last spring, despite the legal issues that served as red flags. Those same coaches were able to convince the Bengals to target receiver James Wright, in spite of the zero catches he had his senior season at LSU. Both picks were among the best the Bengals had last year.

Add those reasons to others outlined in this post from earlier Monday, and you see why Collins would be the ideal fit.

But will he be around at pick No. 21? It's not starting to look like it.

Mocks have started propelling him from being a low-first-rounder into a potential top-10 or top-15 pick. McShay, who hadn't previously had Collins ranked in his top 25 in earlier mocks, shot him up to No. 11 (Vikings) in Monday's.

If Collins is gone by the time the Bengals pick, then they can't go wrong with Peat.

Rated ESPN's No. 2 offensive tackle prospect, Peat was on a bevy of All-America teams at Stanford. He's also the son of former Cardinal and Raider Todd Peat. So his football IQ shouldn't be a question. At 6-foot-7, 313 pounds, his size certainly isn't a concern.
