NFL Nike Player Jersey Cuts

[Spencer]

Hello,

I thought that the Nike Player jerseys are available in 3 different cuts (similar to the Reebok/ Ribon jerseys):
- QB cut
- Skill cut
- Line cut

But now I have discovered that there is also another cut of the Nike jerseys available for the players. The neck tag says L-BK. However to me the Line cut and the L-BK cut seem to be the same. Does anybody know the differences of these 2 cuts?

Thanks.

Line cut is for lineman, so it usually has a longer length that that of a linebackers cut
