To Buffalo:
K. Poulin, Age: 22, 3.5 gold star potential, Position: G (HYB), OV: 73
T. Wilson, Age: 18, 4 gold star potential, Position: RW (PWF), OV: 54
S. Voynov, Age: 23, 4 gold star potential, Position: D (TWD), OV: 78
To Detroit:
P. Leclaire, Age: 30, 3 white star potential, Position: G (HYB), OV: 80
R. Klesla, Age: 30, 4 star white potential, Position: D (DFD), OV: 82
A. Semin, Age: 28, 4 star white potential, Position: LW (SNP), OV: 83
2013 5th round pick
Overall, I think Buffalo recieved some great potential players, Voynov will probably grow to become better overall than Klesla, and the same with Poulin becoming better than Leclaire. The jury is still out on Wilson because of his age but he could become a pretty good PWF.
This helps though with my 3 needs I wanted. It gives me a 2nd line sniper that can fill in right away. It upgrades my backup goaltending situation (god forbid something happens to Halak who has been great). It also gives me a good veteran DFD man who can fill in right away. Voynov just wasn't cutting it with my team this year and I just had way too many TWD and OFD. Overall I think the trade was great for both teams, this gives me the tools to make a very strong cup run this year and possibly next, and it gives Buffalo some great young talent to build on for the coming years.
Also Wilson was expendable in this trade because of what I was getting back, yes he was my best prospect, but he was still a few years away, and I also have a large abundance of 4 star gold players already like: Schenn, Wheeler, Gerbe, Shattenkirk, Couturier, Hjalmarsson, and Orlov. All of which are NHL ready right now.
Edit: I just hope this somewhat radical change doesn't throw the chemistry of my team off.
