In the early days of camp, neither player has stood out that much, but it appears pretty clear that Moore has a legitimate shot at unseating Greenwood if he has a good preseason.
Moore just might be more of a playmaker than Greenwood, who looked really good in camp during his rookie season but has never built on that.
Jenkins is showing good instincts and he also had a nice hit during the inside drill on Friday.
Now, it would seem a stretch to think Jenkins can steal the starting job from Greenwood and Moore, but it's looking right now like he's got a pretty good shot at making the team, which would be a nice accomplishment considering the position change.
As for the starting job, the hunch here is that Moore is going to wind up taking it from Greenwood, who simply hasn't done enough in his first two years with the Dolphins.
