I love the Alonso pick. Alonso basically yielded us Latos. Phenomenal pick in my opinion. He became an instant wild card (or trade bait) for us. We already had Votto, probably knew Alonso wouldn't be our big league 1B, so they picked him knowing his floor was very high. His ceiling maybe not so high, but you could trade him easily after a good start to his minor league career.
The Brewers did the same with Matt LaPorta for CC. These low floor hitting 1B are "relatively" easy to come by, yet teams still like to trade for them.
