They could keep it at a PK for 13 weeks if you guys were within a couple games of each other. Simply because the set up of the contest makes it so easy to gain ground. But it also goes the other way. But surely too soon to think about strategy when it comes to odds and betting.
Shrink could go 2-3 and Fez could go 3-2 then what odds will you get?
Right now it isn't even worth looking at IMO, wait til week 12-13 and hope they are still neck and neck. That way your money isn't tied up, and you have a little more to work with, and where a good weekend or a bad weekend can make you aneasy winner, rather than following picks for weeks on end hoping to see some sort of an advantage.
Obviously if one starts to take control then you might want to look. If someone gets a 5-6 game lead, then it is on. Just have to hope the odds are not outrageous.
