Meh, just from a Ducks perspective, Fowler is 30, put up solid possession numbers this year while starting his shifts primarily in the d-zone, and also produced well offensively. If the market for a player of his caliber is significantly less than $6.5 x 4, I'd be pretty surprised. If he was signed until he was in his late 30's, sure, bad contract, but this expires when he's 34. IMO not an albatross at all.
With Henrique, he's certainly "overpaid" from a value perspective, likely by about a mil or so, but he put up solid 2nd line production (42 pts/58 games) and was easily the top 2 way forward on the Ducks this year. It also expires when he's 34, so it's not like you're paying on the major-decline years.
Silfverberg? Yeah, I agree on that one. I have an irrational dislike for him, which certainly doesn't help me defend him
Voracek was really solid this year, so it's surprising to see him there. For a team with zero cap issues, he's the perfect guy for the growth of that team.
If I was replacing a few here, I'd absolutely add Petry's 3 x $6.5 , which has already started to bite based on his decline this year, Loooooch in Calgary, and Khudobin in Dallas (just off the top of my head...I'm sure there's more...)
