But he will fix his mistakes come season time.
There are a lot of players who tank when they come to Seattle. DiPoto has zero tolerance for tanking. Those guys will get a very short hook. In other words, no more Mike Zunino floundering into a black hole situations. DiPoto would have tried three or four catchers in 2015. Zduriencik got a good catcher in 2015, Wellington Castillo, but then flipped him immediately for Mark Trumbo, without ever fixing the catcher problem. Would DiPoto have signed someone better than Castillo? probably not. But he wouldn't pretend that there wasn't a problem either.
DiPoto sees the GM job as plugging holes. The most seaworthy boat wins. Zduriencik sees it as amassing the best talent. The most talented boat wins. JeDi's strategy is more sound.
If nothing else, the constant trades should make for some interesting reading at SSI.
