It actually perfectly illustrates the point. Great program in the 60s, good success early 70s, maybe a bunch of dumb moves, made a slight comeback from Pitino through Gillen (majority), made more dumb moves, on the way back up.
PC being successful in the 60s and early 70s meant crap because they didn't have the right mold to support it. PC making a Final 4 under Pitino was not followed by the right moves afterwards, same with Gillen in the Elite 8.
Now they are CLEARLY moving in the right direction. Only a moron would look at the past 15 years as a reason why they can't be good, when they are clearly an improved borderline on way of breaking through team.
They will finish BE .500, lose only 1 player, and bring in at least 4 new players next season (2 of whom were Top 100 players, 1 of whom was a Top 150 player, and potentially Ledo, really wildcard, who is a 5 star guy). Even if Ledo doesn't play, they will be ready to break through.
But it takes the right moves to get there, and those are not a guarantee.
