Mediocrity and capability are not exclusive of one another. A coach who only wins half his games is still, by the primary definition of capable, capable of winning. He's also still a mediocre coach. The fact that Crean has already achieved a particular thing, once by your metric, at least twice by mine, shows his capability.
In the exact same sentence you cherry picked, I indicated Crean doesn't coach championship caliber defense consistently, or even half the time. But, in case you need more clarification, I'll give it to you: I meant the first definition of capable (in Tas' link), not the second. And, before you fall back on the "accepting mediocrity" one-liner, which by the way, is the dumbest mutation of all the stupid "true fan" arguments that have been going on here since 2000, "capable of coaching championship caliber defense" isn't good enough, in my book, to keep the IU job. That's true of dozens of coaches in college basketball, if not hundreds.
Only doing it once in 5 years isn't good enough either. If he manages it this year, it will be once every three years, on average, which MIGHT be tolerable, long run if they keep up the offensive production. So, big year coming up. If Coach can't teach this group to play good defense, with all their talent, well, I'd seriously consider moving on, depending on some other circumstances. Spare me the "accepting mediocrity" one-liner.
