No coach keeps lines together 24/7 anymore. Burrows and Vrbata will be interchangeable at times between first and second lines.
Guys like Burr, who has been so consistent (presuming last year was an outlier) the last few years, are valuable partly because they are so versatile.
People who are looking to get rid of him because of one crappy year are missing a couple of things.
One, hockey players have off years. Careers ebb and flow. Does not mean they are done.
Secondly, that versatility is a huge, huge addition to any team. They can plug into so many different situations.
I don't want to keep Burr because he has scored big goals...although he has. I want to keep him because he has a valuable skill set that is still enormously important...and no matter what some people think, is extremely difficult to replace.
