Except that it's not simply for holds. Top MR dominate #3-5 starters and second tier closers in WHIP and ERA, and are competitive in wins. I've explained elsewhere why I like holds, so just search on my name and "holds" and you'll find it. But, holds make you create a more realistic pitching staff, reward managers who stay active and watch the waiver wire, bring a very good group of pitchers into the mix, and are just as valid a measure of pitching performance as wins or saves (in other words, not very good, but fun for the league). Why duplicate pitcher value with K/BB, when you already have WHIP and Ks? Bring something different into the mix.
