Pahlsson's highest scoring season was 26 points in 06/07. In that season, 141 forwards scored 40+ points. There were 180 top six forwards in the NHL. Thus, 40-50 points wasn't something you'd expect from a third line player. Not then and not now.
He was a selke finalist and a lock for the Swedish Olympic team twice. As a pending UFA, he fetched a return of James Wisniewski and a B level prospect (Petri Kontiola). And later he signed three year contract worth nearly $8 mil with Columbus when the salary cap was $53 mil. That's the equivalent of being payed $4.1 mil PER YEAR in todays market.
In other words, Pahlsson in his prime was pretty clearly regarded as a high end third line center.
