So posts like the ones you're marking are valuable, but ones discussing the transaction in the transaction discussion thread are not? Talk about low-effort posting.
Why trade of him, or why the hype? If the former, see
@Wondercarrot's post (+ the fact that, recent actions notwithstanding, there is still a budget in Ottawa). If the latter, well, he's an extremely reliable player with an absolutely unrelenting motor and some sneaky offensive skills - as in, if he could shoot the puck, or even if he was a bit bigger or faster, he could be a really good every-day top 6 player.
I think every Sens fan would have loved to keep him but, well, it's not our money. The loosening of the purse-strings has been awesome, but it can only go so far.
