Quoting: goldie078
If it makes you feel better, Tyler Myers had a similar long contract that costs 5.5. He's not doing much better with stats. Average 54 GP over last 4 seasons.
Assume Myers and Bogosian were a simple swap.
Evander Kane, same trade, then brought 2 future top 6 fwds and 2 4th liners
Brendan Lemieux (2014 2nd rounder, LW)
2015 1st (25th overall, Jack Roslovic, RC)
Stafford (then current 4th liner)
Armia (prospect 4th liner)
You are correct about the current assessment of the players the Jets received, and at the time of the trade I felt it was a very fair exchange of talent. But their projected contributions when the trade was made were very different.
Armia was projected to be a top 6 forward and may get there he has shown improvement.
The average games Meyers played is unfair. He only played 11 games last year. The 2 previous years he played 71 and 73 games as a top 2 defense-man scoring 28 and 27 pts respectively.
At the time of the trade Stafford played 2nd line minutes scoring 19 pts in just 28 games the 1st year and 38 pts (21g) last year, he fell off of a cliff this year.
Lemieux is a dud, will probably never get to the NHL and should not have been drafted when there were much better players available (Ivan Barbashev, Brayden Point, Nikita Tryamkin for example).
The 1st we will need to wait and see.
Typically when a top line player is traded it is for another top 6 forward or a top 4 d-man, a prospect and a 1st. Stafford was the top 6 forward, Armia and Lemieux were the prospects and the 1st.
