It’s time to dig a little deeper.

A little deeper as in the trenches, where, as we know, games are really won and lost in the NFL.

In the first four parts of this 12-part throwback comparison series, we addressed offensive skill positions.

The next three installments will feature tackles, guards and centers. In terms of the offensive linemen, we’ll be looking at the 2013 Pro Bowlers and a few other standout players at the position. In case you're wondering, these performers are in no particular order.

The criteria are multi-faceted and one legend doesn’t fit all. We are talking style as much as anything because after all, the eye test is still the best pop quiz ever. But other factors will be taken into account when making comparisons.

One reminder: This is not a ranking of the eight best tackles in the league. It’s some of the best players at their position and who they remind us of from the distant or not-too distant past.
