For sure Haney was a bit underrated in the past because he is such a silent type of boxer with almost no hype tagged in his name because he cannot really entertain his audience which is true but fate has its own ways and with Haney's hardwork, he slowly climbed through the ranks humbly and now that he is on the top, he is the most sought boxer as he holds all four belts.
It will be interesting and exciting to see Haney fighting Loma or Tank in the future but with Garcia? I don't think so, he will be played by Haney if he fight the latter directly.
Yes I think you can say that, but now he can't be classified as underrated boxer anymore as he already managed to climb the top and became the undisputed boxer in lightweight division.
And I agree, Garcia thinking of fighting Tank is a bad idea and it's too soon for him, he needed to defeat heavy names first like Kambosos or Tank before going to Haney.
