As mentioned in a previous article, the Arizona Cardinals probably and potentially had one of the most successful and aggressive free-agent periods in recent memory.  So in anticipation of the NFL season, I will try to attempt a ranking of the five best free-agent signings during this offseason.

However, most NFL fans know that trying to rank the best signings before the season is almost pointless, because there are always so many factors involved in deciding who are or will be the best or most productive on the football field.

After all, there has not even been a training camp yet that will decide the depth chart. There are also scheme fits that will come into play with each incoming free agent.  Furthermore, there are always injury concerns, that always come in to play in this extremely physical sport.  So attempting to rank the five best free-agent signings can be somewhat hard, but I will do just that.

Here is my best guess at the five best free agent signings this year.
