The Tigers desperately need to replace Valverde. I know some of the talking heads on Detroit sports radio would give up Castellanos in a deal for a closer or catcher. Would a Gregg & Navarro for Castellanos be starting point? Anyone else in the DET system worth targeting instead? I assume J McCann is off limits, since C is such a hole for them. It might be a decent ending point, assuming the starting point was exceptional. Maybe I'm underestimating Gregg's value. Where would you start? You mean overestimating. I'm talking from Detroit's point of view. Gregg's been great for us, and Navarro's been a pleasant surprise, but nobody's going to give up a top 20 prospect for a pair of journeymen, especially with both impending free agents. Even WSR thinks that's madness. I'm thinking that last years Vizcaino trade has lead some think that Theo's capable of outworldly things, when in reality he lucked into a perfect storm. I'm not of the impression that Theo/Jed are going to steal away outlandish hauls of prospects. But, Detroit has shown that they're willing to trade their top prospects to "win now." Albeit for better returns than what we're offering. And I don't expect Castellanos for those 2, but would it surprise me to see Castellanos moved for a need filling package other worldly better than what we could put together? I don't think those players are out there and available, but I'd guess he's moved to fill one if not both of those needs. In comparison, where is Castellanos as a prospect, compared to Jacob Turner, Andrew Miller, and Cameron Maybin were at the times they were traded?
