I was okay with the Briere signing at the time (I wonder if I was a regular poster then; it's pretty close... joined in '04, but didn't really start posting until '07 or '08). It worked out similarly to how I thought his time in Philly would go down: worth the cap hit in the early years, but a decline towards the end leading to a trade to a team needing to reach the cap floor. Instead of the trade, the Flyers get to use a special buyout.
I think the best part of the signing is that the Flyers landed Briere instead of Gomez or Drury, neither of whom I wanted any part of. I was somewhat on the fence about Briere due to his noted defensive deficiencies, but figured he would at least be surrounded by players who could mute them (specifically, Gagne, actually).
With hindsight, it's a no-brainer. His contribution to the run in 2010 will never be forgotten... and his goal to tie Game 7 against Boston is one of my all-time favourite Flyers goals.
