...so if there's a contract sitting on your team you want to get rid of but cannot or will not trade away, then use an ABO.
some teams have posted a post-dated ABO... we will allow - just make sure you make it clearly as post-dated.
finally, the ABO MUST be spread out over the remaining years left on the contract so in some cases you might be better off using a standard Buy Out lumped over 1 yr.
