What do you mean by that...? Any other comments you'd like to be forthcoming with.
While the point match up if you do A+B=C, it's not as simple when you consider both future and present picks
When the trade equation is more like A+Ex(B)/(1+r)^t = C
Where the expected value of the future pick is unknown(there is a large range . in addition the difference in draft strength can't be reliably measured. This is still not taking into account the benefit of having earlier access to talent now as opposed to later.
A real person list manager wouldn't take that kind of trade unless the predicted outcomes were heavily in their favour, they weaken an extremely strong draft position for such a questionable benefit in 12 months time.
They'd have to be an outside circumstances for it to go through, Like an guaranteed on trade that passes on that risk to a 3rd party.
Another thing to have in mind is that these draft points don't reflect trade value (as valued by list managers or their expected value in use which are completely different) where made using a line of best fit using wages earned over a specific time period. IMO they undervalue how much of a premium early picks have compared to picks even just 10 spots later, teams wouldn't trade a pick number 1 for picks 13,14 and 15.
What I mean can only explained in a convoluted manner so I'll just shorten it to say that after weighing up the pros and cons of the trade a list manager who received that offer would reject it as it is far from a fair deal even if you could equate the draft values.
