It looks like Ralph Spry thought the ball was thrown to him...

Spry MAYBE would have made the catch, but in that case a fumble would have occurred moments after. Sometimes I hoped more for an incompletion when the ball was thrown his way.
Sorry to be harsh, I wish every kid would succeed, but that's the way I felt.
