Pretty fair deal if you believe what the points suggest.
Vilardi (now in D+5) : 71gp, 14g, 17a (.44 ppg)
Zadina (now in D+4): 101gp, 17g, 26a (.43 ppg)
I think Zadina would do really well in LA honestly. As a Wings fan I don't mind this, but I also don't think Vilardi is the solution to our top 6C problems. Personally I like Zadina a little better than Vilardi as a winger, so I'd stick with our guy. I could definitely see this one going either way though, and I wouldn't be frustrated if we made this deal.
