A talented player, Marvin Jones was hindered by poor quarterback play at Cal and didn't produce at an elite level. Jones isn't huge, but he's relatively big and can win battles with his size.
Jones' stock rose after running a 4.46 in the 40-yard dash in Indy. That answered questions about his straight-line speed, but it doesn't remove the doubts about his upside.
National Football Post wrote about Jones,
A tall, leaner athlete who for his size possesses natural fluidity in the hips both as a route runner and with the ball in his hands. Isn't as physical off the line as his frame would suggest vs. press. However, displays the ability to set up defenders with a stutter step and then use his length to get into his route. Isn't a dynamic straight-line athlete but plays faster than he times because of his ability to generate a burst initially out of his breaks. Doesn't create a ton of separation vertically, but exhibits good awareness and body control when asked to locate the football.
At 6'2", 199 pounds, Jones has a good frame, but he could stand to add bulk and strength. Jones' slender build hurts him some at the line of scrimmage, and he doesn't dominate like he could.
Jones does possess big, natural hands as a big plus, and is a smooth route-runner. The question with Jones isn't whether he will catch the ball or make plays with the ball, but whether he will get open.
Though he is a good route-runner, Jones isn't talented enough to offer much in 2012. After he adds bulk and improves as a player, Jones could develop into a solid No. 2 option.
The Bengals have standout A.J. Green and Jordan Shipley holding down their receiving corps. Jones could possibly compete for a starting spot this year but we can expect him to mature with playing time.
