I agree with this assessment. Miami did a great job IMO improving the offensive line. In signing Brandon Albert, the team turned a big weakness into a strength. Jonathan Martin was clearly one of the worst starting left tackles in football and Albert is a Pro Bowl player. The draft brought Ju'Wuan James and Billy Turner who both should start. Kudos to Hickey for the moves on the offensive line.
But the other biggest weakness, the linebacking unit, received very little help. I like Jordan Tripp a lot, but I don't see him as an instant starter like some hope. Perhaps down the line. Koa Misi in the middle seems like the best move the team can make because Dannell Ellerbe seems better suited outside. Perhaps Dion Jordan is ultimately the answer at linebacker, although the coaching staff appears to view him only as a defensive end. Any way you slice it, this group is clearly below average -- maybe the only unit you can say that about on the Dolphins this year.
