No, because he is much much better skater than Tavares was, arguably the most critical skill needed to translate well to the NHL. I'd also say he's got better hands and passing ability as well.
We don't even know if he's had a "really good" 9 games or not. What's to say he doesn't have a better rest of the year, making his start look slow?
What would make Tavares the better prospect, other than the fact that he had a really good 16 year old season and then was unable to improve on that?
*Had one of the best 16 year old season in OHL history you mean? As of now McDavid hasn't hit 100 points, Tavares did it 3 times.
Also, his career high season in the OHL was 72 goals and 134 points, McDavid's was 20 something goals and 99 points.
Right now Tavares' career high kills McDavid's. Will McDavid come close or pass him this season? Most likely, and he should if hes a better prospect like you say he is, but as of now he hasn't shown the same offensive outpout that Tavares displayed.
Also, Tavares focused much more on becoming a more defensive player and being NHL ready rather than putting up useless points in 7-0 games in the OHL. This had been noted by his coach and scouts during his last 2 years in the OHL, which is the reasoning for the drop in production until he got traded to a contender again.
Finally, while McDavid is definitely faster, and he has better hands if you mean dekes, Tavares has many qualities that he beats McDavid at.
It is very debatable that skating is the most critical skill to translate at the NHL level as there have been countless examples of kids with speed to burn who coundn't cut it, while many more "slow" players who became stars.
IMO Tavares has better "hands" in the sense that he could finish goals better than almost any prospect I've ever seen. His hands around the net and in the slot were NHL star calibre by age 16.
Its definitely a close call between the two of them, I just haven't seen anything out of McDavid as of yet (besides these 9 games) which indicates he would be a better prospect/player than Tavares was.
I think people forget just how good Tavares was in the OHL, he was being compared to Crosby (and Gretzky sadly) in the same sense that McDavid is now. It'll happen again with the next great 15 year old that comes along as well.
