According to that article, the Rays are setting up their garage sale with some high ticket items, the obvious being David Price. There was another article posted today on fangraphs speaking about the sense behind a Price-to-Cardinals trade in exchange for Taveras. The Cardinals have been putting players on the DL as often as I drink bottles of wine. Acquiring Price for 1.5 years would not block any major prospects for the long-term but it would provide them a formidable 1-2 punch for the second half of the season + postseason. Being a Reds fan, the thought of the Cardinals acquiring Price makes me queasy.
That said, the price for Price will not be cheap and would likely start with Taveras. Not many other clubs can match that caliber of player to give the Rays in return. The Fangraphs article also mentioned that a Price and Zobrist deal for Taveras + makes more sense so the Cardinals can distance themselves from a potential Kozma V.2.
While we dont know for sure if the Cardinals will acquire Price (or others), the writing is on the wall that Price's time in Tampa is limited and the Cardinals certainly have a place to put him.
