Yes! A whole sixteen days older!
I would think more significant is that Toews was drafted two years later than Rielly (108th pick compared to 5th), and only started his NHL career five years later.
Even more significant is the fact that the two players he was traded for haven't even been drafted yet, so how can we possibly assess the trade?
But you're right: he's not a teenager, and Lou and Trotz had him for two seasons. Maybe they accurately assessed what he was worth TO THEM, and decided a trade was best.
