Since coming to town in 2012, in 48 games played by the Dolphins (no playoff trips) they have led after the first quarter in just 12 games (25%). NO TEAM has done worse. Even the lowly Titans and Jets have led after one quarter in 13 games, and the Raiders have done it in 14. Hell, even the Jaguars have led after one quarter in 17 games since 2012.
Getting off to a good start is key in football. Since 2012, teams who lead after 1 quarter win 66% of their games.
So while they might not be getting “manhandled” in 1 quarter, they routinely are NOT leading, which is a problem.
Its not their only problem. On 3rd and short, the Dolphins converted 70% of their runs into first downs, 11th best in the NFL. The problem was they passed on 52% of their play calls, 9th most often, and they converted just 55% of their pass attempts. So they missed out on 15% better efficiency by simply not running enough on 3rd and short.
