James, who left the University of Oregon after the 2011 season, is projected as a top 100 prospect by SB Nation, but barely. He put up gaudy numbers in college but at 5-9 and 195 pounds, there are concerns about his durability as a pro.
The Lions might be extra wary of a running back with James' slight build in light of Jahvid Best's injury problems. After playing all 16 games as a rookie in 2010, the pint-sized Best missed the final 11 games of last season, including the playoffs, because of a concussion.
Still, James is an enticing prospect. He averaged an outrageous 7.3 yards per carry as a junior last season and tallied 18 touchdowns for the Ducks, who won the Rose Bowl. He did, alas, miss a pair of games with an arm injury, a fact that won't help allay injury fears.
