Really dislike that for Oakland.
Puk doesn't even have to improve to be a decent trade chip at the deadline.
Bleday on the other hand needs to change a lot to be above replacement level. He can barrel the ball and take a walk but the problems after that are numerous. Not a good defender, not fast, when he doesn't barrel it's a fly ball and not a line drive plus he has some contact issues (so he may not hit even .220), his raw power is not even as good as you would expect.
Just looks like trading a bona fide MLB LHRP for a AAAA hitter....
