Just because it didn't hurt one player, doesn't mean it didn't hurt the other.
Except your argument that is that it
didn't hurt Fowler, as is evidenced in your discussion with Jays because you're saying he had a great season.
So, if, as you're contending with Jays, Fowler
did have a great season and if, as I'm contending Gormley did as well, then age becomes relevant. The fact is that Fowler will have played three years of high level hockey, before being drafted and Gormley will have only played two.
So, in order to accurately compare Gormley and Fowler, one would have to compare Fowler this year against Gormley next year. Also, I don't give a damn about stats. I've watched Cam Fowler play, multiple times and I've watched Brandon Gormley play. Brandon Gormley is the better defenseman and I know that there are
many pro scouts, also known as people whom NHL teams pay for their opinion, who agree with me.
Fowler is a very good skater. That is literally his only advantage, and against Gormley it's a very slight advantage. Gormley is a smarter hockey player, he's a more defensively sound hockey player, he's just as capable offensively and he's more physical. And given the fact that Fowler is a year ahead in the development curve, it's entirely possible that an 18 year-old Gormley will be
more dominant offensively than an 18 year-old Fowler.
Fowler is an excellent one dimensional offensive defenseman. Brandon Gormley is an excellent offensive defenseman who doesn't give up anything in the defensive zone.
That makes him a better prospect.
