Mono represents a big enough question mark in my mind to knock Simpson down a notch simply because it can really cause trouble for a pitcher when it comes to recovery. It's not like he'll come back at 100% once the mono is out of his system; he still has to not only regain his weight, but also his former strength and stamina. There were already questions about Simpson's size and durability, so this sort of thing just nags at me. It's speculative on my part, but I could see Simpson needing to spend time at EXST next season in order to get back into shape. That would cut into his performance into 2011, considering he won't log as many innings and might also have trouble going deep into games. I grant you, he could be perfectly fine next year and it's all needless worrying on my part. Lots of athletes have overcome their bouts with mono and Simpson should, as well. However, 2011 might be a bit of a bumpy road for him depending on how his recovery goes. Also, for me, mono was one factor of many in why I ranked Simpson where I did (14). Had Simpson been a 3rd or 4th round pick (around where he was ranked pre-draft), I don't think anyone would have him in their Top 30s. I'm willing to give Tim Wilken credit, but I'm not going to buy into a guy just because Wilken picked him in the first round. Finally, the sheer lack of professional experience and data makes it hard for me to get a read on him, especially considering how Simpson's stuff varied over this past season. At least Jin-Yeong Kim got quality time at Instructs, you know? It just didn't feel right to rank him in the Top 10 to me. I'm rooting for the guy to break out and prove the doubters wrong. However, for now, I'm willing to be bearish on him.
