You got put at 13 or on the wing when you were a kid, and since then everybody has just assumed you know what it means. So I've written it down, one backline position at a time: what to look at, and what to do when you see it.
Pick it and you get the short guide for that position, free. It's one page, and it takes about three minutes.
Every pack is the whole job for one position, cut into six parts. Each part has the pictures first, and then the reads, so you can look more than you read. These four are from the fullback pack.
A few quick questions and your email, and it's yours.

Your pack is on its way to the email you paid with, and it should land in the next few minutes. If you can't find it, look in spam, or have the link sent again from the bottom of the positions page.
