So overall:
- Seasons 1/2: if anything, exceeded expectations
- Season 3: slight underdogs, had a real shot but lost in 7
- Seasons 4/5: choked, bad losses
- Season 6: played well but lost a very evenly matched series in 7
That's a rather generous way of framing it, but I get that some want to remain positive.
Personally, the first two I give them a pass just barely. Sure, the were big underdogs in both but it's not like underdogs never rise up and beat the odds. Happens virtually every post-season.
But since then they've had a 3-2 (or better series) lead in the 3 of the 4 and lost them all. Once you can forgive, but 3 in 4 years, sorry, doesn't matter who the opponent is, you had the other team on the ropes in each one with 2 (or more) attempts to finish them off and failed. That's a pattern of choking.
And in the other one (Columbus) they were a no-show in 4 of the 5 games, save for a 3-minute goalie-pulled miracle stretch in g4 to push the series to a deciding game. Then they choked in the final.
So to me, the simplest way to think about it is that it's 4 straight years they were as good or better than their opponent and they lost them all. And the result is that this "breakthrough" we are waiting for, I worry that if they just get to the 2nd round, is that it? Okay, at least they can win one, let's just re-tool for next year?
To me, 7 years with a single series victory is only fractionally better than 6 years with none. A breakthrough should really be considered no less than a conference final.
