It's not that Jarmo makes all the right moves all the time, it's just that Jarmo makes moves all the time. He has a pretty good track record IMO, but more importantly he's shown he's not afraid to make decisions. If anything, the kitchen psychologist in me says he hates a painful decision less than having his hands tied. I believe him when he says it was the best of bad options at the time, but of course that doesn't mean it's not possible better options would've come available later. We also don't know what other moves he was/is potentially hoping to make. I think the bottom line is in the eyes of a lot of fans he's probably earned a pretty long leash.
Could very well be it's a decision he already regrets, but time will tell how things pan out. Then again, he doesn't particularly strike me as a guy who likes to second guess.
