I mean with the way the media has been hyping him up the past couple of years I don't see why he wouldn't ask for that much money. Would be hilarious if he ended up earning more than McDavid. The guy is not even top10 in PPG, he's 12th, just 0.01 PPG above Draisaitl and behind his teammate Marner and quite far behind the top guys Kucherov, McDavid and Rantanen.
Honestly Matthews has to be one of the most overrated players in relation to what said player has actually performed. Only 8 points in his last 10 games and in those 10 games he was held off the scoresheet 5 times, with prior to the Caps game was pointless in 3 straight games and -6. Actually he hasn't been a plus player in his last 8 games and in his last 13 games he has only been positive once. As a whole he is +/- 0 on a team with a +34 goal differential.
Truth is he is a lot closer to Drai in skill level than McDavid. Ironically Drai is +3 on a team with -19 goal differential and has back-to-back 70+ point seasons (Matthews has never even hit 70) and will most likely outscore him once again this year
