Dolphins all-in on O-line?

It's no secret that the Miami Dolphins need to rebuild their offensive line this offseason. Their off-the-field issues are well-documented, but free agency could leave them with no starters at guard or tackle. Of those positions, the Sun-Sentinel's Omar Kelly pegs left tackle as the "franchise's top priority," and he expects them to be aggressive on the free-agent market with about $35 million in open cap space available.
