"What's left?" Umm...how about a LT, Blocking TE, and another pass rusher.
I think the "What's left" comment was in regards to what is still on the market, not what positions need to be addressed.
I know they have $8 million in cap space right now and another $10 million in cap space starting on June 1st ($18 million total), but I have no problem with them turning their attention to the draft now. They made a lot of positive moves in free agency and left only one major glaring need going into the draft(Offensive Tackle). Sure there are still positions like cornerback, tight end and defensive end that need to be addressed with competition and depth, but I see our 11 draft picks(5 in the top 82) going towards addressing those issues. I also expect that glaring hole at offensive tackle to be filled in the draft or perhaps Eric Winston finally caves to the Dolphins one year offer.
The Dolphins are in very good shape right now on the eve of the draft, no need to make any desperate signings.
