"We haven't released anything," Philbin later said of his backfield depth chart, per ESPN.com's James Walker. "We're still evaluating right up until we name our starter. I thought (Moreno) played well."
Moreno is coming off a career year that saw him rumble for 1,038 yards and 10 touchdowns in Denver's runner-friendly scheme. Miller, meanwhile, is looking to bounce back from a disappointing campaign in 2013.
The arrival of play-caller Bill Lazor suggests production for both backs, but Moreno's hot-and-cold offseason had Miller primed to lead the way. It's telling that one strong showing from Moreno has Miami's coaching staff weighing its options.
