Your first point never would happen under the leadership of Beeston (I'm not going there), so it's moot. The Jays have consistently stated they prefer the trade market. Plus, to keep things on topic, I'm not a huge fan of Alvarez; he should have a much higher strikeout rate for the pure stuff that he has. Maybe he develops this as he gets older, but maybe not. At least with Beurhle he's a proven commodity.
They Jays may also be willing to increase payroll; they have stated as much and there's no reason to believe otherwise, with the way the season is going.
I guess my point is that we have proven veterans that are playing well, and there is no way they are in first place had they not given up guys like Alvarez. He may be a great pitcher in the future, but I don't understand why so many people are willing to mortgage the present for the possibility of the future. If you have a chance to make a win now trade, like the Marlins deal, you should be all over it. It turned the Jays into instant contenders, and isn't that what we all want? It didn't turn out great last year, but it sure is working this year.
