I'm in support of the Alex Smith deal and hopeful, since he was quasi-elite or at least top 10 last year, and the Brady's / Brees's have lasted until age 40 recently. Also we probably had no real chance to sign KC. But by history you can see above link over a LOT of QBs reviewed, that the performance declines dramatically every year age>33... Crossing my fingers this $40 million was worth it..
