When it comes to identifying traits in running backs that produce immediate fantasy value, proficiency in pass blocking, ball security, route running and receiving ability are often most important. These traits are valuable because they're important when avoiding turnovers, which is often the difference in a rookie running back playing vs. standing on the sideline.
Opportunity is paramount when it comes to fantasy value, and if a player has to leave the game because he can't identify blitz pickups on third downs, he'll likely miss out on plays when his number is called on either a run or pass play. When that happens, potential fantasy points go out the window.
Tennessee running back prospect Alvin Kamara is proficient in a few of these categories, but not enough to make him a running back you should immediately target in your redraft leagues unless he finds himself surrounded by a ton of talented teammates. He has good hands and turned plenty of screen passes into long runs while at Tennessee. You'll see in the clip above how he's able to use his balance to turn a short pass into a touchdown against ranked opponent Georgia.
Kamara has good balance when he runs and decent hands, even though his hand size is below average for NFL running back prospects. His good pad level also allows him to shed defenders once he gets momentum, but one athletic weakness may prevent him from being effective as a receiver at the NFL level. This is illustrated in the clip below.
Overall, there are some likeable traits regarding Kamara's fantasy value. He just doesn't present a trump card ability which makes me uncertain on how he will win at the NFL level. He has decent hands, but lacks breakaway speed and agility to create yards after catch. He has I'll be avoiding Kamara in redraft fantasy leagues unless he lands in an incredible situation such as Green Bay or Indianapolis.
