I'm throwing the "s" word around too frequently these days, but I think there's merit in the post-hype type of sleeper. One of my favorites this year is Lamar Miller. I talked about Miller in detail a few weeks ago, and found plenty of reasons to like him.
The Dolphins have a completely revamped offensive line, which will be a year removed from tons of drama and horrid play. And don't forget that Miller's athletic ability vaulted him into the third round last season. You can get him this year in the seventh.
Last year, Miller finished with a Rushing NEP of -17.55, dreadful by all standards. However, the presence of Bill Lazor as the new offensive coordinator suggests the Dolphins should run more like the 2013 Eagles than the 2013 Dolphins.
People will be scared off based on last year and the incoming of Knowshon Moreno, but Moreno is already facing knee problems, is overweight, and may not be ready for the start of the season. Whether you love Miller's style or not, starting running backs are always welcome at just a seventh-round price tag.
