It is easy to criticize and praise any trade after the parts have settled. The Lindros trade can be denounced but if Quebec doesn't relocate to Colorado, no way does Montreal trade Patrick Roy to the Nordiques.
Sharp had much to do with the head coach at the time.
The best trades to analyze are what were instantly deemed controversial. Three to consider:
1. Darryl Sittler for Murray Craven and Joe Paterson. Vilified by many at the time. How could Bobby Clarke do what he just did?! The night before the season opener. A future Hall of Famer for.... who?! And then history said otherwise. Craven remains one of the most underappreciated forwards in team history.
2. Certainly the Peter Zezel for Mike Bullard trade. While Zezel had a legion of followers as one of the most popular players with fans at the time, Bullard helped a struggling Flyers squad instantly burn through the League in a trade that had few equals at least initially. Tough to be critical of Zezel but he may have needed a change with Mike Keenan having been replaced by Paul Holmgren. Keenan always liked Zezel even through difficult times.
3. Anyone remember trading Maxime Ouellette and picks for Adam Oates when key players were seemingly sidelined with injuries? The power play needed help. This was a move made for the playoffs. And then zap, out in round one. The controversy eventually fizzled and the trade was for all intents and purposes an afterthought since the moved parts didn't materialize; however, who knows if the Flyers would have used those picks to draft young talent.

The combined (made a few days within each other but joined forever) trade of Dave Poulin and Brian Propp to Boston reeked; seeing them in the Stanley Cup Finals weeks later was a mix of emotions. Clarke had his reasons and those are well-documented, but that was a signal of ripping apart the second most liked core in team history.
Trading Brad McCrimmon was disastrous from day one. Poorly executed and flawed. And McCrimmon wasn't without fault but his skills should have been emphasized.
And perhaps my favorite trade to analyze is Pete Peeters for Brad McCrimmon. Straight up. A goalie for a d-man. The Flyers had a talented goalie in the system named Pelle Lindbergh but were in dire need of blue liners. Boston, just the opposite: desperate for a goalie with a plethora of talented defensemen. Peeters went on to win the Vezina for Boston in his first year after the trade while McCrimmon was OK. In brief... Short term: Bruins. Long term: Flyers.
Getting Reggie Leach from the Seals for Larry Wright, Al MacAdam (decent NHL player) & a 1974 1st Rounder (Ron Chipperfield). While not necessarily lopsided, Leach was a steal.
And Rod Brind'Amour to and fro. His acquisition, presence and departure, was omnipotent in all directions.
