Seeds and brackets

As in the 40 Years Tourney, I am designating the four "regions" with the first names of the Beatles: John, Paul, George and Ringo.

These are the seedings:

1: 1961 Yankees, 2017 Dodgers, 2017 Astros, 2017 Indians
2: 1961 Tigers, 1924 Senators, 1924 Giants, 1961 Reds
3: 2017 Nationals, 1924 Robins, 2017 Cubs, 2017 Red Sox
4: 2017 Yankees, 2017 Diamondbacks, 2017 Rockies, 2017 Twins
5: 1924 Pirates, 1961 Orioles, 1961 Dodgers, 1924 Yankees
6: 1924 Reds, 1924 Tigers, 1961 Giants, 1961 Braves
7: 1924 Cubs, 2017 Brewers, 1961 White Sox, 1961 Cardinals
8: 2017 Cardinals, 2017 Angels, 2017 Royals, 2017 Rays
9: 1924 Browns, 1961 Indians, 1961 Pirates, 1924 Athletics
10: 2017 Marlins, 2017 Mariners, 2017 Rangers, 2017 Blue Jays
11: 1961 Red Sox, 2017 Pirates, 2017 Orioles, 2017 Athletics
12: 2017 Braves, 1961 Twins, 1961 Angels, 2017 Padres
13: 1924 Indians, 1924 Red Sox, 1924 White Sox, 1924 Cardinals
14: 1961 Cubs, 2007 White Sox, 2007 Reds, 2007 Mets
15: 2017 Phillies, 2017 Giants, 2017 Tigers, 1924 Phillies
16: 1961 Athletics, 1961 Senators, 1924 Braves, 1961 Phillies

The brackets were set up with the following restrictions:

• No first-round matchups between teams from the same league-season (i.e, the 1961 Orioles and 1961 Twins can't meet in the first round)
• The different iterations of franchises must be in different brackets.
