If you take Green replacing Miller for example. Truthfully, for quiet leadership probably impossible. Miller was the consummate professional who always put his team before himself. Replacing his skill set at the height of his career, extremely unlikely. Miller was one of the best blocking, surest hands tight ends of his generation. However, replacing end of the career Miller, highly likely. And in fact Green will most likely create much more match up issues. He probably won't be near as in sync with Ben in terms of being the safety valve, but I bet he creates a lot more room on the field for the underneath by the wide outs. And Miller has been my favorite player for the past ten years.
