MIAMI GARDENS — Zach Sieler is my choice for Dolphins MVP this season. There’s no reason to get creative about saying that. So I’ll just say that Sieler, the seventh-year defensive lineman, the gritty, self-made, pull-yourself-up-by-your-bootstraps guy who lived in an RV (recreational vehicle) early in his career, is my clear choice for Dolphins MVP. Sieler, a Michigan native and dedicated outdoorsman, leads the team in sacks with 8.5. No one makes big plays in big games more frequently than Sieler, who leads the league’s No.
