There has been a lot of talk about replacements this week, but luckily it appears that our long, national scab-referee nightmare is coming to an end. However, that doesn't mean the talk of replacements will end. That's because Week 4 marks the start of bye weeks in the NFL, making Flex Spending all the more important.
The first three weeks of the season have been a cakewalk. Anyone can field a competitive team when they have their entire roster at their disposal. Now that a handful of teams will be sitting every week, your depth will finally be tested. It also means the new faces -- the replacements, if you will -- could end up swinging games, making it absolutely necessary to stay up on who's coming and who's going at the flex position.
