I think people have gone overboard in praising Hurley, but you're going a little overboard in the other direction.
You failed to mention that 8 of those 12 years were spent at Wagner and Rhode Island. Not exactly traditional powerhouses. Wagner won 5 games the year before Hurley was hired, and in year one he improved them by 8 wins. In year two, they won 25 games. He inherited a 7-win team at RI, and they got steadily better, reaching the tourney his last two years.
Wagner's been to the tourney twice in its entire history. Rhode Island's been to the tourney twice this century. Both teams were coached by Hurley.
This take is as disingenuous as claiming Scheyer did something amazing by getting loaded Duke teams to the 2nd round and regional final.
