I agree - that's why he cost nothing but a lottery ticket. We were just hoping to catch lightning in a bottle. I suspect they thought a new voice or a tweak in his approach may unlock something as well. Same reason they grabbed Sanchez when Santander went out for the year. Sometimes you don't catch that lightning. If it were easy to do, everyone would do it.
I applaud the GM for not sitting on his hands - he's shown some urgency to add/plug holes at reasonable/low cost. Those will always be long shots. I guess the criticism is that he didn't got bigger and get more proven bats. I'm not sure it was critical enough at the time that we wanted to start emptying the farm.
Injuries to Kirk, Springer, Barger and Lukes, combined with Vlad and DS sh*tting the bed has made it near impossible for any secondary move like to really have much impact either way. I think if Atkins would have known that this is what would have happened, he may have taken another approach - but I don't think anyone would have predicted this (except for a few of the most knowledgeable fans of all-time of course, who just knew this was going to happen).
