It's rare that you have a player who's a perfect mirror image of a current NFL player. So typically what you do is you throw out a couple names of comparable players to give the readers an overall picture of what to expect from a given prospect. You could say Frank Gore and Ryan Moats represent the range of Ray Rice's potential in the NFL.
I think most people understand the comparisons and find them helpful. I'm sorry if you don't.

Enjoy your fantasy football team by drafting Ryan Moats 5th overall.
Moats is a very valid low end compare. Look at this predraft write up of Moats:Ryan Moats, RB, Louisiana Tech Bulldogs

The 2005 NFL Draft is becoming famously deep at the running back position. For a good portion of the draft season, Louisiana Tech RB Ryan Moats was flying below radar. Lately, though, he has been getting some well-deserved attention. Moats' idol is former Detroit Lions RB Barry Sanders - both in life and on the football field. Like his idol, Moats is wise beyond his years, is a high character individual and very difficult to tackle. His decision to come out early was based on the belief that he would be overlooked for his height no matter how well he might do as a senior. Instead, Moats wanted to spend that year earning a spot in the NFL.
As a high school sophomore, Moats suffered a leg injury, initially believed to be a deep thigh bruise. It turned out to be much worse. He had a staph infection that damaged his femur bone. He went threw multiple surgeries and was told he'd never be able to play football again. Fortunately, his bone began to heal and by the start of his junior season, he was near 100 percent. During his senior season, Moats finished with 2,646 yards rushing at 9.2 yards per carry, including 33 touchdowns on his way to breaking the Bishop Lynch High School all-time rushing record (4782 yards).
Despite his production, the big schools were scared away by Moats' size and he ended up at Louisiana Tech. In 2002, he saw action in ten games, and did most of his damage as a kick returner while backing up senior RB Joe Smith. The 2003 season was a breakout year for Moats, earning first team All-Western Athletic Conference honors for his 1,364 yards and 10 touchdowns. He also broke the 200-yard mark twice.
As a junior in 2004, Moats became WAC Offensive Player of the Year and a semi-finalist for the Doak Walker Award (best running back). He set school records with 1,774 yards and 18 touchdowns. Moats broke 200 yards in five games, including 236 versus Fresno State, adding an 83-yard touchdown run in that game as well. Moats currently ranks second in school history with 3,176 rushing yards.
Strengths
When watching him, you can see why Moats would choose to model his game after Barry Sanders. He has those same thick legs on a compact frame. Moats can change directions on a dime and accelerate past defenders. His quickness, balance and ability to cut are his best assets. Some questioned his long speed, but Moats answered that with a 4.46 40 at the combine. Moats shows good strength for his size and can power through tackles with his strong lower body. Moats is an asset in the passing game, showing good hands and a willingness to block. Scouts and fans alike love Moats for his great character. He's a humble young man that believes if you put yourself above people, you have farther to fall. The East-West Shrine Game sent an invitation to him, a rarity for underclassmen, and he had one of the better weeks of any player there. Moats is a competitive player, and never wants to come out of a game. So much so that he will sometimes hide injury and fatigue from his coaches.
Weaknesses
The big knock on Moats is his size at 5-8, 210 pounds. That is good weight for his height, but he won't be able to get much bigger. His lack of size limits his ability to run inside with power. He'll have to start his career as a third-down back and kick returner until he can prove to be a feature back. Although Moats is a willing blocker, his size hurts his effectiveness.
Summary
It's hard to ignore Moats' production and explosiveness. He has a similar game to current Philadelphia Eagles RB Brian Westbrook. Both players are low to the ground runners, who can catch the ball and make things happen in the open field. Moats will most likely start his career as a role player, but could find himself in the starting lineup sooner rather than later. Moats will be a fan favorite for whatever team drafts him, which should come as early as round three.

It is evident to anyone observant that EBF is doing two kind of compares:
1) Who the player is built like and seemed similar to in college.
2) Who he projects to be like, in a range, at the NFL level.
As for good luck drafting Moats 5th- that was just a snarky comment.
You are acting like a seventh grade boy trying to to seem smart, and just not pulling it off. Top 5 busts happen all the time. Moats was a first round pick in most dynasty drafts, he usually went between 9-12, near Eric Shelton. In the past few years- JJ Arrington, TJ Duckett, William Green, Deshaun Foster, Mike Williams, Charles Rogers etc.
