Interesting. If that article is accurate - and there's no reason to believe it isn't - then it sounds like trading Suzuki is the prudent move. If he won't sign a reasonable extension before the season ends, there's absolutely no reason not to trade him in the next ten days.
And how better to prepare the fans who will be upset about a trade, than to have something like this leak. Good news in my book as a trade looks very likely. The Twins are going to have so much money to blow next offseason that if they really want him back for his unevitable slide, they can easily overpay him.
As to the buy/low sell high issue, Ryan has done well in the offseasons with Span and Revere. I think those that are frustrated (me included) take issue with not getter better return for deadline deals.
However, somehow the Twins have been in the terrible position of being awful, with hardly anything of value to sell at the deadline. Willingham in 2012 and Perkins last year were about it and neither were rental players. Liriano, Young, Doumit and Morneau all struggled come deadline time. Many of us wanted the Twins to move them the prior offseasons when they had value, but who knows if teams were even interested.
