I'm not sure other agencies were as concerned about the S2. The real reason we haven't heard about the s2 scores are A) teams are keeping better control of the results and B) the media hasn't chased the scores.
Stroud didn't "beat the odds". He flipped the test on its head and spun it like a top. How can anyone trust a test that the developers said would filter out QBs that can't play. And it filtered out one of the greatest rookie QBs in football history. It was a huge failure of the S2.
As I said last year prior to the draft, there were not enough data points to make that conclusion. S2 tried to rig the results from the beginning, testing and releasing the results of Drew Brees. "Hey Brees did great on the test! That means it works!" Um, did they go back and test Ryan Leaf, David Carr, or Joey Harrington? Nope, don't need to know that. The S2 is a failure until it is not. And that will take a number of data points that you and I won't see in our lifetime.
