Let's do some Noam Chomsky on this thread.
Title: "Matthews will be a total "Sakic" aka Tavares"
Knowing how to read quotes and the underlying need to quote Sakic presents the fact that this phrase is being used to indicate that the subject of this title, Matthews, is being labeled as one determined object, Sakic, but is ACTUALLY being labeled as another, Tavares.
This can be noted using prior notice that, when he was draft eligible, Tavares was being lauded as a Sakic-type player, with some going so far as to say that Tavares would be Sakic in term of ability, consistancy, and impact to his team and the NHL.
At this time it has been noted that Tavares has NOT lived up to the adulation he was given in his draft year and has not trended as Sakic did. At the approximate number of games played, Sakic had produced at a far more significant number than Tavares. As well, unless the NYI win the Stanley Cup this coming season, he has not proven his ability to lead a franchise to the overall win.
Furthering to the title, I am safe to say that the title means: "Matthews will be the next Sakic, exactly like Tavares has turned out, meaning he didn't; so Matthews won't."
Safe to say that if Matthews DOES trend as Tavares did, and is, Toronto will be in a good spot as the complimentary developing players Matthews has are far superior than that was available for Tavares.
Besides, we already know what nationality Matthews and Sakic are, so what nationality is Tavares?
