Thanks but that's stuck behind a paywall.
I found another article that's free that talks about it:
C.J. Stroud pushes back on cognitive test score reports ahead of NFL draft: 'I play football'
Apparently, being hungry/tired can affect your score, and you can do better in a retest. So how valid is this test compared to one that just tests your physical attributes? I dunno, but processing what happens on the field at rapid speeds, seems relevant for the QB position. Stroud apparently scored a '19' which is horribly bad, 80 and up is the number that talent evaluators are looking for. In comparison Bryce Young scored a 98, Will Levis a 93, and Antony Richardson a 79.
But the S2 test guy said that one of the leaked scores is 'inaccurate' is he talking about Stroud, if not then who? This score getting leaked literally affects a player's draft stock which could cost them millions of dollars due to change in draft position. OOF.
