Question About Added Length Initials Found On Reebok Jock Tags - NFL Jerseys

[TriplexXxSports]

We have all seen a Reebok jock tag with a (i.e. 4" L.B.) flag tag, or something similar. With that said......

1) What does the 'L.B.' stand for exactly?

2) Has anyone ever come across one that says (i.e. 4" L.I.)?

3) If so, what does the 'L.I.' stand for?

Am I answering my own questions by saying that they stand for the style of cut?

I feel slightly foolish asking this but until just recently I have not seen a 'L.I.' tag, only the 'L.B.' tag.

Any thoughts? Here's a couple of pics for comparison.
