I rarely think about that game -- I was a freshman, and I was crushed -- but I always thought a definitive turning point was when Magloire stretched Wojo. I recall thinking Wojo just wasn't the same after that, and in that sense, Avery might have been a better option down the stretch. But I'd have to watch the whole thing over to remember, and I have no desire to do so.
Personally, I liked the idea of Gbinije and wanted to see what he was made of, though I'm not particularly fanatical about it. I didn't think we saw enough to really make any sort of conclusions one way or another about his defense, though I tend to think his athleticism and size could have been an asset on a team that was short on both. And a potential time investment definitely had upside, especially when Duke got late in the season and didn't have any actual small forwards. But when it comes down to it, very few really know what goes down behind the scenes.
