The 2012 fourth-round pick is pegged to replace veteran Reggie Bush as the Miami Dolphinsí starting tailback. Miller showed plenty of flashes last year when he led Miami with 4.9 yards per carry.
But we haven't seen much of Miller during the preseason. The Dolphins have only given Miller nine carries in three preseason games. This is a player who could get as many as 20 carries per game in the regular season.
Are the Dolphins being too cautious with Miller?
Miami is expecting a breakout year from Miller as a first-time starter. However, it's hard to gauge where Miller currently stands when he averages just three carries per preseason game. Also keep in mind that Miller has just 51 carries in his NFL career.
