I think you're overstating the pens lack of drafting and development ability. They've brought up numerous support players over the years from their AHL team that they would not have been able to win without. Yes the pens were gifted Crosby/Malkin, but they've been run extremely well top to bottom over the years. They have the active playoff streak record in both the NHL and AHL right now at 12 and 16 years respectively.
You’re gonna have to mention names to prove your point here. They’re widely regarded as having one of the worst prospect pools in the league and it hasn’t produced many notable players in recent years.
Their NHL team has Crosby, Malkin, Letang, Murray (and Fleury previously). So I don’t see what relevance it has to their prospect pool and drafting ability in the here and now. Playoffs in general don’t mean much because of how many teams make it, but the AHL playoffs don’t have a ton to do with prospect pool strength either. Guys like Leighton win goalie of the year awards and guys like T.J. Brennan are among the best scorers at their position.
It’s a mix of prospects and tweeters/guys not good enough for the NHL. More prospects play in junior leagues, high school/college, and overseas than they do in the AHL.
It’s pretty simple though, if you disagree they have one of the worst prospect pools then start naming blue chippers. If you think they aren’t a bad drafting team in the here and now then name some blue chippers, youngsters on the NHL team, etc.
