More than those 3 were keen.
A summer calendar meant players doing pre season from the 2nd week of January, playing mid Feb until end of June, a "break" in July which was actually just 4 weeks of training for the vast majority (not actually a rest or break), then run again August till the end of November before spending 2-3 weeks re-building sides to get Xmas and New Year week off and back to it.
Players, mostly volunteer club and coaching staffs were running on empty. A summer season at least allows an end in the last weekend of May and players are signed until the end of June allowing teams to get proper respite before starting pre season in July.
The only difference in the game schedule in the 1st 2 weeks of December and 3 weeks in January, where teams would have done pre-season in years gone past.
