... Buying a player from another organization there is still a chance that player can be an impact player. Chances are it may be low but there still a chance. ....
You're absolutely right that there is still a chance that the player can be an impact player. The problem is that it will happen very, very rarely when the team that has been developing him for several years is giving up on him. Non-zero does not mean substantial nor that it is nearly as good as the chance was when the player was drafted.
Say you draft an 18 year old at a point in the draft where his chances of turning into a marginal depth player are 10%, a solid NHL player are 5% and his chances of turning into a top line forward or top pair defenceman are 2%. You can play with those numbers if you'd like-the exact numbers aren't important to my point.
Four or five or six years later considerably more has been seen of him and his chances have changed immensely.
That 10% chance of him becoming a marginal or depth player will hae changed. It may have improved. He might even have already gotten to that stage so you might get a chance of close to 100% that you're getting someone who can be among your top 9 defenceman or top 15 forwards.
But what is the value of that top 9 defenceman or top 15 forward? Yes, every team needs them, but they aren't hard to find, aren't hard to acquire. You can find players close to that level every year in August accepting professional tryout contracts and you can find them every July as free agents whose agents are making phone calls trying to drum up interest for. You don't need to spend assets to acquire those players. A good system will get them automatically as drafted players mature and develop.
Now returning to that guy you're considering trading for four or five or six years after he was drafted, the chance of him becoming that top line forward or top pair defenceman you hoped for when he was drafted have really, really dropped. Teams that are giving up on players like, for instance, Adam Clendening or Brandon Leipsic or Linden Vey, are doing so because they don't think the player is going to turn into a good NHL player. The problems in his game will be fairly obvious and that 2% chance of getting a top line forward or top pair defenceman are probably now more like 0.01%. That 5% chance of getting a solid NHL player will have dropped to less than 1%.
That's why those of us who criticize the direction of wanting other teams' prospects in trade instead of picks have been doing so. We'd rather have that 5% chance of a solid player than the 100% chance of maringal scrub or better with a less than 1% chance of being a solid NHL player.
The marginal guys are easy to obtain for very little. In the long term it isn't necessary to trade for them. They are worth almost nothing in trade. Your chances of getting impact players through the draft are far higher than they are getting players who other teams are giving up on after trying to develop them for a few years.
A 5% chance is better than a chance under 1%. Getting those <1% developed players will occasionally lead to a trade won, but more often lead to a roster full of mediocrity, which the Canucks have right now. The point we make is that this mediocre roster is the most likely result of the direction the Canucks have taken, not that it was preordained and the chance of being good were zero.
To take a revised lottery example, if I were to offer you the following for 50 cents which would you choose:
-a ticket with a 60% chance of winning 10 cents, 20% chance of getting $1 and a 1% chance of getting $10, or
-a ticket with a 10% chance of winning 10 cents, 10% chance of winning $1 and a 5% chance of winning $10?
Taking the 1st ticket is like taking the known marginal player with a very small chance at something worthwhile. You'll get something back on your ticket far more often (81% of the time) but if you do that 100 times you'll "win" $36 for the $50 invested.
Taking the ticket with a higher chance of getting nothing back but a higher (though still low) chance of getting something worthwhile is more like the draft pick. If you take that bet 100 times you'll win $61 for that $50 invested, even though you get nothing at all back on your ticket 75% of the time.
So in one case you "win" something 81% of the time but end up losing heavily based on the initial investment, while in the other case you only win something 25% of the time but come out ahead.
Benning's direction of targetting other teams' castoffs is like the first ticket-high chance of some almost useless return and very low chance of a good return.
If you have unusually superb pro scouting, then it is possible to beat the odds against making that kind of trade and uncover a few real gems. At this stage, after the trades and free agent signings that have been made over the past four seasons, it is impossible to make a logical argument that Benning's record in pro scouting is good enough to beat the odds with that kind of trade. His team has become exactly what one should expect from targetting other teams rejects-few impact players and an abundance of mediocre ones.
