This is going to be the Oilers lot in life for the next several years, hate to break it to you, we have to take chances on opportunities like that (specifically former 1st rounders who may click here).
We're not going to have many 1st round picks in the future, probably not even many 2nd round picks and those that we have will take 3-5 years to come into their own which is outside of our immediate window.
Our drafting the last 10 years has been shit and the good players we did draft we let get away except for Bouchard.
Klim Kostin and Podkolzin like opportunities are exactly what have to be looking for, to not do so is pure negligence. Players perform differently on different teams, we see that all the time. We should have taken a chance on Dylan Strome two years ago too, now the cost of getting a player like that would be through the roof.
Kostin scored at about a 16 goal rate here with no time alongside McDavid or Draisaitl, no time on the PP, I have doubts even a guy like RNH would have 16 goals in that situation. Then had a couple of big goals in the playoffs, and played physical with speed and is still only 25 years old, was a 1st round pick himself. If you can get a player like that for a 4th round pick, you'd be stupid to not do it. The odds of getting a better player than that in the 3rd or 4th round is maybe 0.5% and even if you hit pay dirt on a pick that, you're probably 5-6 years away from them contributing.
