I wouldn't say RB is off the list of needs. Edmonds is great for depth, and a decent receiver, but he's not the workhorse RB that Miami needs. Miami needs a 1,000 yard rusher, and Edmonds isn't going to be that guy, unless the OL is miraculously the best in the NFL next year.
His stats are excellent in small doses. Talking about high on the leaderboards, but he won't rush 300 times in a season. That's okay though, I think we can work stuff out with the guys we have now or someone off the heap. RB is not where you spend big as Dallas now knows.
