I agree with that point in isolation, but let's do the maths here:
(3rd in league + 1st in Scottish Cup) > (2nd in league + knocked out of Cup at first hurdle)
Let's face it whatever our own clubs achieve is the best in our eyes and nobody will tell us any different. However, in my red tinted specs it takes 38 games to finish a league campaign (10 points clear of third,also had nothing to play for for our last 5 games (let's face it Celtic had won the league already). However, it took Caley 5 games (6 including your replay against St. Mirren) to win the cup. However, I also see your view.
