Whilst I don't disagree with your statement, I believe he gets a fair share of improvement

Giordano becomes a better keeper than Burns (increase in Shots, Hits, and Points)
Iginla becomes a way better keeper than an even more aging Cole (big increase in Shots, Hits, PPP and Points)
Sedin is indeed a small-mid downgrade to Ovechkin (less in PPP, Hits)
Ott just provide compensation in Hits for Ovechkin's loss

There's no denying Ovi is the best player in the deal. Perhaps 2 1st rounders seems heavy, but considering the way he manages his team (weak keepers), the 2 of the 3 players I'm offering are definite improvement.
