Sam Bennett - Sam Bennett (season before his Calder rookie year)
Sean Monahan - Sean Monahan
Johnny Gaudreau - John Gaudreau (before he tried to grow the facial hair and had to shorten his name to appear older then he looked)
Sven Baertschi - Sven Baertschi (before he found his two way game... two way for him at least)
TJ Brodie - TJ Brodie (a less stronger and less mature brodie)
I think he's saying the players will simply grow into more mature versions of themselves and cannot usefully be compared to anyone else. At least, that's my take....
