Just going off spnited's great list here. My changes in bold, comments in italics:
Atlanta/Milwauke/Boston Braves: Henry Aaron (Absolute no-brainer)
Arizona Diamondbacks: Luis Gonzalez (Can't disagree, although Randy Johnson could make a case, too)
Baltimore Orioles/St. Louis Browns: Frank Robinson George Sisler (Not easy, not easy at all; Robby had too many of his great years with Cincy, so I sided with Sisler because he had twice as many PAs as a Brown than Robby as an Oriole; Ripken and Murray -- who had some pretty damn good years with the O's -- are next in line)
Boston Red Sox: Ted Williams (Absolute no-brainer)
Chicago Cubs: Ernie Banks (Absolute no-brainer)
Chicago White Sox; Joe Jackson Frank Thomas (Big Hurt -- a legit choice regardless -- also had 6K more plate appearances for the Sox than Jackson)
Cincinnati Reds; Frank Robinson Johnny Bench (Robby, hurt again by the fact that he spent so much time elsewhere -- but, man, Bench was a friggin' legend)
Cleveland Indians: Bob Feller Tris Speaker (Just preference here; Feller wasn't even best pitcher on his team after '47)
Colorado Rockies: Larry Walker Todd Helton (Overlooked, and for good reason due to Coors factor, but Helton's numbers are a shade better)
Detroit Tigers; Ty Cobb (Absolute no-brainer)
Florida Marlins: None I can think of (Pretty awful that Luis Castillo leads more categories than anyone else ... him or Conine)
Houston Astros: Craig Biggio (By a nudge over Bagwell)
Kansas City Royals: George Brett (Absolute no-brainer)
Los Angeles/Brooklyn Dodgers: Sandy Koufax Zack Wheat (Controversial choice -- but damn, Koufax had five great years for the Dodgers; Wheat had 18. The fact that he's still the franchise leader in G, AB, H, 2B, 3B, TB, RC, and second to Snider in a few others, 80 years after he retired ...)
Los Angeles Angels: Rod Carew Garret Anderson (Another controversial choice, but check out the <a href="http://www.baseball-reference.com/teams/ANA/leaders_bat.shtml">franchise leaders</a>: G.A. leads in a ****load of categories. Clearly, Carew was a better player -- but strictly as an Angel? Anderson's the best.)
Milwaukee Brewers/Seattle Pilots: Robin Yount (Absolute no-brainer)
Minnesota Twins/Washington Senators: Walter Johnson (Absolute no-brainer)
New York Mets: Tom Seaver (Piazza's No. 2, but it's really not that close)
New York Yankees: Babe Ruth (Absolute no-brainer)
Oakland/Kansas City/Philadelphia A's: Jimmie Foxx (Tougher than it seems; Double X *barely* beats out Rickey Henderson, Al Simmons and Eddie Collins, but all four have <a href="http://www.baseball-reference.com/teams/OAK/leaders_bat.shtml">strong cases</a>)
Philadelphia Phillies: Mike Schmidt (Absolute no-brainer)
Pittsburgh Pirates: Roberto Clemente Honus Wagner (Roberto's next, but the Dutchman is one of the top 5 ever -- absolute no-brainer, to me)
St. Louis Cardinals: Stan Musial (Absolute no-brainer)
San Diego Padres: Tony Gwynn Absolute no-brainer)
San Francisco/New York Giants: Willie Mays (Absolute no-brainer ... but Mathewson is close)
Seattle Mariners: Ken Griffey Jr. (Absolute no-brainer)
Tampa Bay (Devil) Rays: None I can think of (Crawford, I guess. If I have to.)
Texas Rangers/Washngton Senators: Alex Rodriguez Ivan Rodriguez (Tough one, but Pudge has 4x as many PAs with the Rangers as A-Rod -- and as many MVPs.)
Toronto Blue Jays: Joe Carter Carlos Delgado (Not really close, either)
Washington Senators/Montreal Expos: Tim Raines (Yeah, over Dawson and Guerrero)
