Fryatt was Jimmy Frizzell's first signing in 1970 when we were second bottom of the Football League. He completely transformed the team and the expectations of watching it. We got promoted the next season and didn't look back for a quarter of a century.
That is why, in my opinion, he is the most significant. His signing started it all.
Ritchie was a fantastic player and a brilliant signing, but only one of several around that time.
