More heavily projected, yes. Quite possibly more highly regarded, although Papelbon was considered a high caliber starting pitching prospect. More polished, heck no. He had to work pretty dang hard to refine his command to the point it is today and he was topping out at 91 when he came up. although I'm sure the cancer played a huge role in that. Papelbon was much more clearly a big league pitcher in 2006.
Before they made a closer with him, Papelbon was very much considered an heir to Schilling and even in the wake of 2006, it was a heated debate whether it was better for the guy to go back into the rotation. And he probably would have done a very good job as a starting pitcher. I often wonder how history would be different if we'd made the other call in '07. Oki probably would have been our closer by May, and he was very, very good that year, but the Gagne bust would have been magnified and I'm not sure we win the Series, even with the better rotational pitching. Going forward every year since we probably would have had a better shot though, which makes it interesting and tough.
