Hey guys, it's been a while but I decided to come back and give my opinion on this issue. There has been so much press about the factors in Papelbon's sudden move to the bullpen, be it his own desires, the team's necessity, and what have you. In my opinion, none of this matters. All that matters is that he is now the closer, and how this effects the team. I think there are several factors that need to be considered when looking at this move.
The first and most obvious, is how Papelbon will perform compared to how he would have performed as a starter. You can look at this in two different ways, as a scout and as a stathead. Being a Baseball Prospectus subscriber, I have been following his PECOTA projections recently. As a starter, he would have been projected to have an ERA of 4.03 and win 10 games. As a reliever, PECOTA projects him to shave off almost exactly a point to 3.04. This is because, as a general rule, relievers don't usually translate to great starters. I think that stats show that he will be an ace reliever, but maybe not have a future as an ace starter.
When you look at Papelbon from scout's perspective, you see two great pitches. Blazing fastball. Dirty splitter. After that, he really doesn't have another major league pitch. Yes, he might be able to improve his curveball, and yes, anyone can learn to throw a decent changeup, but as it is now, Papelbon has ace closer stuff, and middle of the rotation starter stuff. We also don't know how much his stuff will suffer as he gets deeper in the game. To me, we will get most value out of Papelbon being a starter.
Another important factor is Papelbon's health. I am by no means an expert, but I have never heard of a reliever being in more jeopardy than a starter until the Papelbon situation. I really have a hard time buying the idea that turning him into a starter will save his arm. That is all I am going to say on this issue.
The only factors left to consider are short and long term results the team will have with this move. Many people are calling this a shortsighted blunder; one that will be good for this season but not for the future. I couldn't disagree more. For one thing, PECOTA projected the Red Sox to win 93 games with Paps starting, and it has lowered this projection to 90 with him closing. This can be explained by having Tavarez as our number five starter rather than Paps. So if it's not good in the short run, why the hell would we do it?
Here's the reason. Having watched Jon Lester pitch last season, I think he has ace material. If he can comeback from the cancer treatment, which supposedly went as well as it could have, and he can improve his command (he's 23 for crying out loud), I think he will be hurling quality starts for the Sox by at the latest. If Papelbon were starting, we would be down an ace reliever and also would have two many starting pitchers.
What I think lots of people are forgetting is that Papelbon is 26. He still has 10+ years as a major league pitcher, hopefully closer to 15. If Hansen becomes the reliever that everyone thought he would, it is not impossible for Paps to go back to the rotation again.
Also, in his ROOKIE year, he had one of the best seasons a closer has EVER had. If he even approaches those numbers over the next decade (hopefully as a Red Sox), he will be sure bet for the Hall Of Fame. I really think people need to stop complaining about the move and be happy that we get to watch Papelbon more than every five days.
