White was not worth a second round pick. He wasn't worth a second round pick when he was drafted. I think everyone saw that at the draft too. If we could have gotten a second round pick for him, he'd have been gone long ago.
Lukowich wasn't a terrible contract. It wasn't good, but he was 7/8/9 guy at 1.566 which was a bottom pairing cost. Ehrhoff cost 3.1, or 4.666 ish including Lukowich, who we submarined immediately, and Ehrhoff redefined our defenses role in offense. A negative to tack on to be sure, but one year at Lukowich's cap hit was a coup for Gillis in getting Ehrhoff for almost nothing.
We gave up White and Rahimi, neither played a game for us, or for the Sharks, and if I remember correctly, it was plastered all over these boards that precious few of us had much hope in them playing. Nothing we gave up, collectively or individually, was worth a 2nd round pick. We gave up nothing but two roster spots, got a cap dump and top four D. This is the definition of a cap dump from the Sharks.
Booth and Reinprecht and a third round pick for Samuelsson and Sturm was even. Samuelsson didn't have a lot of gas left in the tank (although I was sad to see him go), and Sturm wasn't a quality signing, both of whom were set to expire. Booth, a year of Reinprecht's salary and a pick for that was a great pick up too, at the time. In hindsight, Booth didn't work out, but it was the risk we should have taken.
Both trades are very similar. We receive a player that is an upgrade to our roster, with term and a higher cap hit then their team can afford, we send back players to accommodate the new contracts, and take back a single year of a overpriced contract. We gave up no value, took back salary in the long term, and the other team's motivation of getting cap relief is well documented. I like the Ehrhoff trade better then the Booth trade, as it turned out better, but that's all in hindsight too. Both are very, very similar structurally, we just took more years and more cap hit in the Booth trade, but compensated by sending cap back.
