It's not a "take". It's a statement of fact. Period. Tubby was, on average, more or less the same coach at Kentucky with his own recruits or Pitino's. Period. These statements of fact cannot be argued against. You can say that Kentucky was in decline before he left, but that is an entirely different argument and not at all germane to the (false) point that "Tubby couldn't win at Kentucky with his own recruits".
Oh, and to answer your idiotic and pointless question, Pitino went 14-14 (10-8) in 1989, his first year, and Sutton went 13-19 (8-10) in 1988, his last year. Yes, Tubby's last two seasons were the worst since the two previous coaches they had. Contrary to Kentucky fans' belief, their team is not automatically handed a minimum of 12 conference wins every season. Tubby was just so terrible at Kentucky that his successor was way worse.
This man has helped this program. You conveniently look at now, and 5 years ago, and ignore the years in-between, wherein Tubby has been more successful than any Gophers coach in over 20 years. How convenient for your argument.
