When someone says something like, "That is arguably the best move I've ever seen!" does it make you go "huh?"?

In the last five years (that I’ve noticed, anyway) people are starting to use the word “arguably,” in place of “unarguably” and it seems silly to me. Everything can be “argued.” However, if a sports commentator says, “Micheal Jordan is, unarguably, the best basketball player of all time,” it gives a little more weight to his opinion, but it can STILL be argued, of course.
