actually, to add to this, often we hear guys like homer and smyth being called untalented, and yes part of getting their job done is being willing to go there and take a beating, but yeah they had hands for days. great hand-eye coordination, great timing, very smart players in general.
in general i think the common denominator between guys who played for a long time on successful teams with superstar linemates is brains. holmstrom, burrows, mike knuble is another one. some players when you put them with a superstar put up points but might just break even or be a net negative because they also impose a tax on your superstar. dany heatley is one example: alfredsson scores more points than ever before but he also needs to pull a lot more weight being the dirty work guy on that line. whereas the guys i just mentioned make life easier for datsyuk/zetterberg and the sedins and thornton/murray and forsberg/gagne and ovechkin, and so on.
