One thing the Jets must consider when dealing with their free agent wide receivers is how well they compliment each other. Braylon Edwards and Santonio Holmes are just about perfect together. Holmes is a fantastic route runner who can do damage underneath. Edwards' ability as a deep threat gives Holmes more room to operate. If a defense focuses too much on the short stuff to Holmes, Edwards can burn them long.
On the same note, Holmes has enough speed to get deep himself. If a defense keys too much on Edwards, Santonio can beat that defense long. The reality that defenses need to account for Holmes' vertical ability gives Edwards more space to operate than he would have if he was the only vertical threat.
Both of these guys are accomplished wideouts who would have success on their own as long as they had good quarterback play. The Jets offensively, though, benefited a lot from having both in 2010. They would continue to benefit from this arrangement not changing.
