Brown was suspended for four games in March for violating the league's policy on performance-enhancing drugs. He later revealed that the suspension was for using Adderall, a prescription drug he said he has used for medicinal purposes since entering the NFL.
The 25-year-old Brown spent the 2011 season on New York's practice squad. He has not received any playing time during two seasons with the Giants, but the team has kept him around because they consider him especially gifted.
Per the SB Nation Giants blog Big Blue View, running backs coach Jerald Ingram said the team is still excited by Brown's upside, but wants to see the 6-foot, 240-pound back demonstrate a heightened awareness on the field.
"Really the thing that has held Andre back is just learning the offense," Ingram said during a press conference Thursday. "He's big, he's fluid, he's strong, we drafted him so that he could catch the ball out of the backfield. He really is gifted. Athletically, he might be as good as anybody out there. But his ability to learn in a lot of people's offenses, because he's had the world tour, that has been his weakness. Now, he came back last year and showed that he actually could learn some of the things that we had done, and as he progresses and gets that opportunity, he has the size to pick up 250-pound linebackers. He's got physical toughness, he has got great hands, he has that ability but can he put it all together is what we're interested in seeing finally, has he matured to that level of being an every down back?"
