The program puts a XX in there for the largest margin, but doesn't accredit you with picking that team. He can pick Jax again.
The XX is for missed weeks.
If there's a duplicate pick, it shows the team he picked twice and deducts the points for the largest losing margin. He can still pick Jacksonville because he hasn't picked them yet (picked Seattle twice).
On a non-related note, JimC: why is the link on your site to the Margin Pool linked to SurvivorPool.htm, but with the Margin pool standings? Shouldn't it be Margin.htm? Do you just rename the page every week? Seems like an un-necessary step to me. ^8
