I can promise you one thing, Jordan Staal is not overated. I am from the area, and he is definitely deserving. The Thunder Bay Kings are not doing too good this year but Jordan is doing all he can (something like 49pts in like 27 games). He is supposed to be the best of the bunch, which certainly isn't fair to him since his brother is Eric Staal, but the potential is there. Huge frame, 6'3", and not skinny like Eric, built about 185lbs, for a 15 year old.
Really though, he is a tremendous talent, he really looks like Modano when he skates (not comparing his to Mo, just saying he skated like him), phenomenal hands. There is a real buzz about this kid around that area. WILL go in the top 2 of this year's OHL draft, that is assured.
And to answer your question, I don't know why it matters, but yes, Jordan and Marc get along really well (i guess you're hoping to land him this year), as do all four brothers. Eric, Marc, Jordan, and Jerrod are extremely close. They grew up together playing on their backyard rink. They all have each other to thank for what they have accomplished, and what they will accomplish. NExt Sutter brothers.
