Poll results: Dolphins' offensive line

This is the time for optimism in the NFL. Despite various flaws, every team around the NFL believes it has a chance to make the postseason and perhaps a run at the Super Bowl. Regular-season games ultimately will determine that starting in September. But for the next month or so every team likes its chances.

On Monday we examined concerns and storylines for the Miami Dolphins heading into training camp in our latest SportsNation poll. The Dolphins also believe they are playoff contenders, but they must answer several questions in training camp.

According to Dolphins fans, Miami’s reconstructed offensive line, which will have five new starters in Week 1, is the biggest question mark heading into training camp. There are major concerns now that Pro Bowl center Mike Pouncey is expected to miss about 4-6 games. This category received approximately 40 percent of the vote.

A close second, according to Dolphins fans, is Miami’s new offensive under Bill Lazor. The Dolphins struggled mightily last season under former offensive coordinator Mike Sherman. Lazor is expected to bring an aggressive, up-tempo scheme to Miami. Lazor's offense received about 39 percent of the vote.

Quarterback Ryan Tannehill's development in Year 2 was a distant third with fewer than 20 percent of the vote. Miami’s linebacker switch involving Koa Misi and Dannell Ellerbe barely registered in this SportsNation poll.

Dolphins’ training camp begins Friday at 8 a.m. ET at the team’s headquarters in Davie, Florida. I will be there reporting all the latest from Miami’s practices, so bookmark ESPN.com’s Dolphins page.
