It's not a bad thought, but here is the pattern that I have noticed with Snider.
Sometimes he is mashing AAA, and sometimes he struggles even at that level.
When he is crushing AAA and promoted, he continues that success at the MLB level for awhile.
But after a month or so, he deteriorates.
I think this is partly due to pitchers adjusting to him, but also partly because he gets away from the things he has learned in AAA, and DM does not seem to be a good fit for him.
If there was a way to have Mottola up in MLB with him, I think he could find sustained success at that level.
