The left tackles will be on parade here at the NFL scouting combine like beauty pageant contestants on a runway through Tuesday.

Lumpy, hairy, 4-XL contestants, that is.

The draft prospects will go through the drills, interview and undergo physicals.

The veteran free agent offensive tackles won't be here, but their agents will be. And they will be trying like pitchmen in mall kiosks try to sell cell phone minutes.

That means a lot of left tackles will be shopped over the next six days.

But the Bears might not end up with one who can beat out J'Marcus Webb in training camp.

That's right, Webb is starting to look like he might have the pole position to be the Bears starter next season.

Why is that?

Let's start with the draft.

There are three left tackles considered NFL-ready in the 2013 draft — Luke Joeckel of Texas A&M, Eric Fisher of Central Michigan and Lane Johnson of Oklahoma. What has become apparent in recent weeks, and is likely to become more apparent over the course of the combine, is the trio of tackles will be off the board by the middle of the first round.

That would be several picks before the 20th spot the Bears hold.

D.J. Fluker of Alabama also is likely to be a first-round pick, but he is believed to be a right tackle and likely would not be a threat if the Bears selected him.

There are others in the draft who eventually could develop into starting left tackles, most notably Florida State's Menelik Watson, Arkansas Pine-Bluff's Terron Armstead, Syracuse's Justin Pugh and Wisconsin's Ricky Wagner. But NFL executives aren't currently talking them up as first rounders.

That brings us to free agency.
