I said before with Gurriel's emergence, the Jays are really only a legit CF away from having a very strong position player core, which is one of the reasons I can understand the Fisher acquisition even if I can nitpick on what we gave up or question how good he actually is/can be.
The pitching is a different story. I think we all hope the magic Shapiro and his GM's had in Cleveland with pitching can translate over. Too early to tell. Thornton looks like an inconsistent back end starter ATM, but right now he's the only one you can somewhat rely on. How Atkins and co can develop pitching in the upper minors (Thornton, Merryweather, Waguespack, Pannone, Kay, SRF, Diaz, Perez, Murphy, Zeuch, etc) will be interesting to watch. The lower minors pitching prospects look really good, but can we develop some of the fringey guys we have in AAA/the bigs?
