Whatever excuses Lebron fans want to make, it's still a bad look on his legacy. In the NBA going to that many finals is a big accomplishment but considering a player on a basketball team plays a more important role than a singular player in any other major sport. If this happens LeBron supporters would say the Warriors are just too good to beat. Maybe in terms of the series yes that argument is passable though it's still excuse making. When it comes to being swept there are no excuses. The Cavs and Warriors were destined to meet in the finals since before the season started. There's no reason the Cavs can't at least make it interesting. If they don't it may be a knock on LeBron's legacy that he won't be able to bounce back from in the discussion of the greatest player of all time.
As far as the quality of the series, it has been uncompetitive and boring to watch. This is especially bad because the playoffs have been just a path for both to blow their way through to crash into each other. That's a good not great storyline but if the finals continues to be pointless to watch because games are over by the start of the fourth, that good story holds no reader's (viewer's in the cases) attention.
Do you remember that word problem where the two trains are traveling at 100 miles per hour on course to intercept one another, when will they collide? At this point The Cavs' train will be parked at the station in Cleveland at roughly midnight eastern time Friday into Saturday defenseless when the inevitable Warrior train rams not just into but through the Cavs'.
As a fan of sports who can't decide who to root for I sincerely hope this doesn't happen. It's bad for the sport and it's bad for the enjoyment of the unbiased fan watching. Thus far the Cavs' train has shown no signed of starting up but only time can tell.
