If they do, it certainly won't be in the first round because of more pressing needs at other positions and because of the presence of Ronnie Brown on the roster.
So it would seem that regardless of what happens with Williams, more help is needed at the position.
But the fact the Dolphins had not had a single visit or workout with a running back as of this week might speak volumes about their intentions.
Still, we can't help but think the Dolphins should add a running back during the draft. When depends on which running backs are available when it's their turn to pick.
With that in mind, here are a couple of running back prospects who could be of interest to the Dolphins at some point.
Lorenzo Booker, Florida State: Booker didn't have a great career at FSU after arriving there with a lot of fanfare, but he's a guy who probably will become a better pro. Booker's stature and speed have drawn comparisons to former FSU star Warrick Dunn, although he might not be as durable as Dunn has proven to be. Booker has the look of someone who could make a very good third-down back. He figures to get drafted around the third round.
Michael Bush, Louisville: Bush was considered a possible first-round prospects entering his senior season, but then he broke a leg in the season opener. His stock has since dropped to the point where some now think he might not go before the third or fourth round. The bottom line is that Bush is a big, highly productive back with a knack for finding the end zone. He would be awfully tempting in the third round.
Ramonce Taylor, Texas College: Taylor began at the University of Texas but left because of off-the-field issues. He looked like a future star during his one season with the Longhorns, helping his team to the national title in the 2006 season. He could be worth a flier in the sixth or seventh round.
Chris Henry, Arizona: Henry could have been had in the mid-to-late rounds before a tremendous workout at the combine moved him up the charts. Still, Henry could be of interest in the third round.
Gary Russell, Minnesota: Academic issues led to Russell leaving Minnesota after he had teamed with Marion Barber III to give the Gophers a tremendous 1-2 punch. Then Russell hurt himself at the combine with a horrible showing in the 40-yard dash. But none of that changes the fact that Russell showed great running instincts and toughness during his time at Minnesota. He's another guy who could be worth a look in the sixth or seventh round.
Kolby Smith, Louisville: Smith became the feature back for the Cardinals after Bush's injury and he turned in a productive 2006 season. Smith isn't as good a prospect as Bush, but he's a versatile back who also has the look of someone who could help on special teams, something both Minor and Morris did for the Dolphins.
