I disagree about playing 1B. Although some stiffs have played there over the years, there have been many outstanding fielding 1B.
A good 1B gives confidence to 5 of the remaining 8 players on the field. The mediocre fielders in the rest of the infield know that their throw can be in the dirt, high or wide and the 1B will protect them.
The good to great fielders in the infield won't be afraid to try a spectacular, but chancy, throw if they have confidence in the 1B. Otherwise, they might be tempted to hold onto the ball.
What other position player catches more balls in play, except the Catcher? From the 2B, SS, 3B as well as the Pitcher and Catcher. He covers down the line as well as toward the hole at 2B, in addition to his primary area.
Maybe I'm partial because I'm a lefty and really enjoyed playing 1B when I was younger, but I took pride in instilling confidence in the majority of the position players. Even at the height of 5'10".
