1969-70 / 1984-85 deadheat
1962-63 3rd
1986-87 4th
2013-14 comeback when you've won the title....but not the worst I've ever seen
It's all about opinions, I know, but my favourite of the Kendall era is the 85-86 side, which won nothing. Desperately unlucky, that's all.
I won't try and compare any of them to the 1962/63 team, too much of a time gap, but geez, they were bloody good.
