Pens fan here!
Iggy has looked solid, but hasn't lived up to the hype thus far. Its weird in that the thrill of getting him was so immense, but he's kind of just slotted in as a nice decent addition to the team. I haven't really heard many praises or complaints. He's shown his amazing shot, hands, etc at times but other times appears to float a little.
He does appear to be heating up a little (I really just think he had 0 chemistry with Geno). People talk about the Crosby line, but last year the most productive line in hockey that couldn't be broken up was Kunitz - Geno - Neal. I'm hoping for that line and Dupuis-Sid-Iggy when everyone is back.
Another reason for him sliding in the background is how great Jokinen, Morrow, Murray have been. It hasn't been as pretty, but the Pens keep winning without Sid, Geno, Neal, and Martin and on most nights it appears to be in large part because of the new guys.
He appears to be fitting in well with the locker room though (no surprise) and apparently hangs out a lot with Morrow
Decent article on the pairings stay here in Pittsburgh thus far
