2011 Community Projections Review: Colby Lewis

Getty Images

Colby Lewis had a shockingly successful return to Major League baseball in 2010. He gave the Texas Rangers a 3.72 ERA in 201 strong innings with peripherals of 8.78 K/9, 2.91 BB/9 and 0.94 HR/9. The community projections were very bullish on Colbyashi's chances to repeat or improve on his 2010 numbers and he had the best numbers of any projected starter for 2011 with many expecting him to be the best pitcher in the rotation instead of the Opening Day starter, C.J. Wilson.

Unfortunately, compared to what was projected, Colby was very disappointing. As a very inexpensive pitcher he had a pretty decent year, but it was a big step down from his 2010 season. Strikeouts went down and home runs allowed nearly doubled. Colby was a mix of strong and terrible starts... his game by game variance was the highest of any Rangers starter [despite the Derek Holland narrative]. We later found out he was dealing with a hip injury throughout the year, but ultimately Colby's season was well below expectations.

Using a Root Mean Square Error (RMSE) approach [lower is better] the top and bottom individual projections have TideNTexas at the top of the projections and PM Productions at the bottom.
