And if we dig into the archives, most of us said the same thing about Doc after year three and his 2d NIT bid in 3 seasons.
The windows for Miles is not 6 years, really, it's more like 3. Same as Doc and Barry. If he doesn't have quality recruits in by that time, years 4-6 are most likely going to be just like Doc's. And voila, new coach. Even worse now with the facilities, since if you can't use them as a magnet your first 3 years, then magnet it will no longer be.
He has 2 classes to land the bedrock talent to advance. That's a lot of pressure.
