Spahn and Sain and pray for rain.
Here are some guys that just missed out on making the all-time team:
Johnny Sain: Sain was half of the Braves great duo in the late 1940s along with Warren Spahn but, unfortunately, he didn't have enough sustained success to earn a spot. Sain spent five full years in the Boston Braves rotation, plus most of a sixth season, going 104-91 for the organization. Sain led the National League in victories in 1948 and twice led the league in complete games, but with a deep pool to choose from there are better choices.
John Clarkson: Clarkson is a Hall of Fame pitcher from the 1800s who led the National League with 49 wins in 1889, but the reason he missed the list is because he only spent four and-a-half seasons with the Braves. Clarkson got to Cooperstown mostly because of his performance as a Cub, so that's why this Hall of Famer missed out.
Old Hoss Radbourn: Another Hall of Fame pitcher from the 1800s whose best years were with the Providence Grays. In his four years in the Braves organization (then the Boston Beaneaters), he actually had a losing record of 78-81.
Tommy Bond: Bond had an amazing three-year stint with the organization starting in 1877 where he had back-to-back years leading the National League in wins with 40 each season. As if that wasn't enough he had two ERA titles in a three-year period while leading the league in shutouts for those three consecutive years. The reason he's left off the list is because he only pitched four full years in the organization, which keeps him behind some other pitchers with longer resumes. Bond was the last guy cut from the list.
Vic Willis: Willis is a Hall of Fame pitcher from the early 1900s who spent the bulk of his career with the Braves. He won 151 games but also lost 147 and twice led the National League in losses. Willis had a very strong career, but so did the guys who made the team.
Steve Bedrosian: Bedrock appeared in 350 games with the Braves and collected 41 saves. He pitched six full seasons with the organization during two stints along with parts of two more seasons. His All-Star selection and Cy Young Award came with the Phillies, so while he was good with the Braves, he just didn't do enough to beat out the guys who did make the team.
John Rocker: I have to start out saying that I am not a fan of Rocker as a human being, but he deserves mention for what he did on the field. Rocker was great in a setup role for the 1998 team as a rookie, then saved 38 games the next year before the now infamous Sports Illustrated interview. He did add 43 saves over the next year in a half with the Braves before being dealt to Cleveland. Rocker's career playoff resume in a Braves uniform was also great, as he never gave up an earned run over 19.2 innings. His 181 strikeouts in 125.1 innings between 1999 and 2000 are almost Craig Kimbrel-like.
Jonny Venters: Venters has only been in the Major Leagues for two seasons, but he's been one of the game's best setup men each of those years. Venters has pitched an incredible 164 games over those two years, but what's more incredible is that fact that his ERA has been 1.95 or lower in each of his first two seasons. If he had more time in a Braves uniform, he'd make the list as I thought very hard about including him.
Greg McMichael: McMichael was a key piece of the early Braves dynasty, saving 40 games combined in 1993 and 1994. In his five seasons in a Braves uniform he had an ERA of 2.96, but it's his postseason resume that keeps him off the team. McMichael's playoff ERA is 6.32 over 19 postseason appearances.
A few others that I felt were deserving of at least a small mention would be Charlie Buffinton, Tim Hudson, Rafael Soriano, Kerry Lightenberg, Kent Mercker, Rick Camp and Kevin Gryboski.
