I love how you conveinatly leave out Miller's 14 game stint with Tampa in which he recorded NO points and was a -3. Makes you wonder how much playing on a good team with a better record influences/motivates a player, huh? In addition, despite all of Pisani's injuries and inferior linemates his stats prorated would be mearly 3 points less of Miller's total production. When you factor in ice time and linemates, Pisani would almost have certainly surpassed Miller's production.
Couple that with the fact that Pisani's goals agaisnt average per 60 min of pk time was FAR BELOW that of both Miller's and Eave's, despite being on a DRASTICALLY worse team, and it becomes harder and harder to argue that Miller outplayed him enough to warrent that much more money last year.
You are looking at simply the stat line, instead of situational statistics such as quality of oppositsiton faced (hint... Pisani was the highest on the Oilers), and quality of linemates + Ice time. I suggest you dig deeper into the stats before you throw out ones that our clearly unfair to compare.
Pisani averaged more ice time than both Miller and Eaves. And while Edmonton was certainly terrible, neither Eaves nor Miller were playing with particularly great linemates all the time. May, Maltby, Draper, Helm, Abby, Williams, Leino...not that much different from Horcoff, O'Sullivan, Moreau, Gagner, etc. Miller may have played a bit with the likes of Flip and Cleary, but you're acting like he spent the year on the top line with Pav and Hank or something.
And I'm not sure what kind of math you're doing, but Pisani was on the ice for 10 PPGA in 91:42 (~6.5/60 min). Eaves was 13 in 147:54 (5.3), Miller was 7 in 120:31 (3.6).
Pisani is 33, hasn't played more than 56 games in the past three seasons. He had one decent season and a great playoff, and has been going downhill ever since.
Miller is 26, coming off his first full season in the NHL, and makes only $150k more.
Eaves is also 26, just had somewhat of a bounce-back season after two down years, and makes only $250k more.
Not saying Pisani is terrible, or that it isn't a good signing. He's fine for a 4th line role. But I'd much rather have the younger guys without potentially problematic diseases, even if they do make a little more money.
