I put a lot of weight on many things, stats, MVP voting, winning, etc. I'll have to check the stats again. But Yogi won THREE MVP awards. I am not saying that Yogi had a higher "peak value" but a higher "career value". Bench lead his league in several offensive categories including HR and RBIs several times. Very few catchers have done that. But over a career Yogi is more valuable because Bench didn't age well. But in Bench's peak seasons he was more dominant than Yogi. I look at MVP voting because this is where "intangibles" will show up. For instance if you have a player who hits .260, 10 HRs, and 60 RBI but finished in the top 5 in the MVP voting that means something. That means that on the spot observers believed that this player had valuable qualities that didn't show up in the stats. So I ask myself how many time was a player a viable MVP candidate?
Here are the top 10 MVP voting finishes for Yogi and Bench
For seven straight years Yogi finshed in the top four in MVP voting. It is obvious that Yogi was on of the top 2-3 players in the American league from 1950-56. Johnny Bench just isn't in the same league when it came to season to season consistency. But it is also obvious that Bench's peak seasons were greater than Yogi's. But if I had to have one catcher for an entire career it would be Yogi.
Some people might say that Yogi was "helped" becasue he was on great teams but so was Bench. Look at Bench's MVP type seasons. In those five years the Reds won:
1 World Series
3 NL Pennants
4 NL Western Divison titles
So the Reds finished 1st in four of the five seasons listed above (The Reds finished 2nd in 1974 winning 98 games!).
