Yep. But it's important to consider that while not everything he's touched has turned to gold, he's got a pretty good batting average so far.
Also important to consider that if Waddell does leave, we won't know whether Dundon was right or not right then and there. We'll know if/when he is right if the front office takes a downturn.
Dundon's hypothesis is that way more than 32 people in the world can do this job at a high level. We seemingly have one right now. But who's to say whoever comes in behind him won't also be great?
It's easy for us to say "why tempt fate and mess with a good thing?", because it's not our money and it doesn't affect the cap in any real way. Pay him $500,000, $3 million, $5 million, what's it to us? Most of us probably don't even know where to find GM salaries anyway, they're immaterial to even the average die hard fan so who cares Tom, pay up! But if Tom is right, and there's many others that could do this job at an equal level and a lower-than-average salary, and that salary savings helps us spend to the cap year over year? Then all of the sudden he's on to something.
