Losing their first match to never lose again isn't the same as being overwhelmed their first match to figuring him out and slowing him down. What did Suriano do different? Nothing. What did Gross do different? Nothing. RBY is the only one who fits the narrative. No idea about the Micic match at Cliff Keen, but in their last match it looks like DeSanto closed the gap from their second meeting, similar to how he looked better against Fix the second time around. We also have examples of the exact opposite. Gomez destroying him in their first match, but then DeSanto majoring him in the second match at NCAAs. Same with Mueller. Gets beat at Cliff Keen (twice?) and then majors him at NCAAs. Beats Lizak the first match, loses at B1Gs, and then wins at NCAAs.
Gomez isn't an NCAA finalist like Lizak, Mueller, Fix, Gross, Micic, Suriano, and RBY, but it still goes to show that sometimes DeSanto is the guy who does better after the first, second, third, etc. meeting.
Your claim that it's typical and that *all* the top guys can adjust after the first go around is just not true.
