It's about as close to a 100% lock or a statistical certainty or whatever you want to call it as you can get that he is far and away the best player who will ever play for Washington and very likely there will never be even a close second, third, or fourth... and people are actually sweating the details of his next contract. Can pretty easily tell who became a Caps fan -- and probably a hockey fan, at that -- during the Ovi era since it seems clear, to me at least, that they don't understand how impossibly rare it is to have a guy like Ovechkin on your team and on top of that, to have him want to stay on your team his entire career and to be able to enjoy the longevity of the career he's had.
The actual dream of being a sports fan is to get to watch a once-in-a-lifetime talent get drafted by your favorite team, rewrite the record books, go down as one of the all-time greats to ever play the sport, deliver your city a championship, and retire having only played for one team and people actually think that trying to use his cap hit for any reason other than to make sure he retires a Cap is an idea they should entertain. Give your heads a shake.
