If the Falcons cut Jamaal Anderson, he will come pretty cheaply. It is difficult to imagine too many 4-3 teams willing to pay top dollar for an end who does not rush the passer well. That is the most important job of a 4-3 defensive end. Anderson's best fit is probably in the 3-4. He, however, does not have any experience playing in that scheme. His lack of a resume playing that specific role would likely prevent him from finding a big offer awaiting him.
That would make it a buyer's market for an end who is a proven run stopper, which has a lot of value. There is some upside. Anderson's athleticism was good enough to get him into the top ten of the Draft. He is also only 24 years old.
Now he is not necessarily ever going to be an impact player, but Anderson has the tools to be productive in the right environment. It seems like a potentially good bargain.
