You need to agree on keeper rules before the draft.... and let everyone have a chance to understand them...
We wen't through several iterations, where we had to scrap it, and start over... but we are in our 3rd year of this set of rules and it is going well...
We allow up to 3 keepers on a team.... you can keep players drafter AFTER round 3... and it will cost you round drafted - 2.... so a 4th rounder will be this years 2nd rounder... a 18th rounder will be a 16th rounder...
This keeps the first round interesting, as the proven studs are still there... and it rewards folks for drafting well...
We put a cap of 3 years on a team for a keeper....
This year we have some good players being kept, so by the end of the 3rd round it's more like middle, late 4th...
We have Larry Johnson (2nd), Lamont Jordon (14th), Ronnie Brown (2nd), Willis McGahee (2nd), Chester Taylor (12th), Willie Parker (6th) all being kepts, along with Steve Smith (2nd), Larry Fitz (3rd), Anquon Boldin (14th), and Antonio Gates (13th) being kept... some of the late ones (Boldin, Gates, Jordon) are keepers from the previous year....
It's been a fun situation... and also our draft is based on a combo of worst to first for the playoff teams... and we have a loser bowl to decide picks 1 - 6.... winner of loser bowl picks 1st, etc.... winner of the super bowl picks last and down from there...
Good Luck....
