From a draft guide that you have to pay for CJ Spiller was number 1 ranked talent prior to the draft. Followed by Ryan mathews, Jonathan Dwyer and Jahvid Best
For positional traits he was ranked best in Best Athlete, outside Run, Best hands, Best After Catch, Best Instincts and Best Intangibles. Best wasn't ranked best in any catagory - others being inside runner, goalline runner (Jonahtan Dwyer and Best blocker - toby Gerhart and Most Durable Anthony Dixon.
A little from CJ Spiller's review
"Fast compact senior tailback displayed big time talent as one of the nation's premier playmakers over his Clemson career, CJ combines all the athletic talent to become a top NFL feature back with well rounded skills including impact return skills, He has natural running skills including terrific vision, excellent cutting skills and top sped to run inside as well as make the big play regularlyl. he shows soft sure hands as a reeiver to rank among the best in that role in recent memory,
though not fully utilized in that capacity as a collegian.
Tough productive tailback ....He is a fine goal line runner with good quickness and fine power that should warrant a key role in a pro offense. He is similar to current backs marshawn Lunch and Julius Jones who were tough college starters and NFL feature backs. (until they ran into trouble) Hindu Theory Tiki Barber
Javid Best - Quick junior tailback had a fine career in the Pac 10 earning conference honors over his final two seasons. Jahvid is an athletic back wi a fine burst of speed that ranks him with the top runners in this class. He explodes through the hole to the second level with the speed to make a big play. He is a smoot runner who fllows his blockers well showing the ability to make defenders miss, slide laterally and break tackles....... As a prospect, he is a very good athlete with a fine skill set for the position to be an immediate factor in a pro backfield, best as a 1A type of runner without being a workhorse back. His ability to pick up th blitz may determine his early pro playing time.
Fine athlete with the taletn and physical abiltityto be a factor early as a pro. His natural running and recieving skills will givan an offense an immediate boost if used properly....Initially as a pro, he will compete for starting time and has the development to be a good chang of pace and 3rd down back. Hindu theory Leon Washington
Hard to say - but I still believe the cream will rise to the top. For immediate help - Best as he is in the best situation - but long term - I think Spiller will be the one.
