I posted these stats in a response in another thread, but it's very relevant to this one.
Compare the first 2 full seasons between Cousins and Brady, and Cousins, literally beats Brady in every category, perhaps with one exception, and does so in BOTH YEARS, and often beats him in impressive fashion.
Add to that, you can expect Kirk to get even better, since he has continued to improve, and also add the fact that his talent around him should continue to improve, and then no doubt, playoff wins will follow. You HAVE to pay the man, and keep the man, no matter what any team offers in a trade.
