That's like saying, "Look at Knight's record at IU, but don't consider 1973, 1975, 1976, 1981, 1987 or 1993. Other than those years, his results at IU were just ok."
For all of his success, IMO Knight's most amazing coaching job was during the 88-89 season. But on paper, that was "just" a BIG title and a Sweet 16 birth.
You can't just arbitrarily take successful years away from a coach's resume and then judge the results. Some "successful" coaches (like....say, Matt Painter) have never gone to an Elite 8 or Championship game, yet Beard has done exactly that in back-to-back seasons.
Beard wouldn't necessarily be my first choice, but even w/o his link to RMK, he's proven himself to be a pretty damned successful coach. IU could do far worse.
