I wouldn't call it an infatuation or irresponsible at all. The Reds have a legitimate chance this year to contend for a playoff spot. Prospects are nice and all, but the goal is to win at The Show and the easiest way to do that for a small market team (like the Reds) is via trading prospects. Speculation has circled the Reds are trying to make a trade for Cliff Lee. Alonso and Wood seem to be the names that have popped up most.
In the case of Mesoraco, I would really prefer the Reds do not include him in any trade.
