I think he is a great WR prospect. A few things on Jones:
a. Played WR at Oklamoa with 3 other NFL WRs (Mark Clayton, Mark Bradley, and Travis Wilson). So, his talents were somewhat overlooked coming out of college.
b. Big play WR. On the Titans, who are void at WR, Jones has a ton of opportunity in front of him. Drew Bennett is expected to leave via free agency, thus leaving Jones as WR1 for the Titans (depending on free agency, the NFL draft, and Givens' comeback).
c. Played very well last season (2005) before injury (knee, iirc)
Most see Jones as a WR in the WR35-50 range for this offseason and going into next season. But, with Vince Young at QB, there will be some great games and some poor games for Jones. He is not a WR yet that you can start each week without hesitation. But, he is a good, young WR in an improving offense under a growing QB.
Jones is 6'3", 215 lbs and pretty fast. He is a game breaker.
