Obviously he was tanking. BUT he did hit the MWR.
If the world has an issue with when in the season you need to get your wins (to Mike's point that all those games he dumped late were with potential playoff teams), then you need a new rule.
Of course, more strict owner screening would have let you know this was what you were going to get. Check out his history. Plenty of instances of "take over team, lose 100+ for several seasons, then try to win."
Looks to me like he trotted out a mediocre 4-man rotation most of the season, paid enough attention to spot start a 5th man earlier in the season, but then abandoned that at the end. Again, this guy knows what he's doing, has a pattern, and executed it to perfection.
Next season will be more of the same if he sticks around
