Hard to say about making the playoffs at this point, but for week 1, I'll say Houston, Indy, Miami, Cards, Vikings, Broncos.... , but i'll admit, just a guess here. But besides that point, there are some starters and many backups that i don't think are as effective as Kaep would be.
Not sure you can say adding 2 win is pointless and what's to say it wouldn't be more... Houston, a playoff team last season yanked its starter today, now they have a highly regarded rookie, so maybe Kaep doesn't fit in , but it should give some teams pause.
