It is just two days into training camp, but Darrius Heyward-Bey is not off to a good start.The talented receiver, who is only 26 years old, has been a disappointment for most of his career while playing with the Oakland Raiders, so it isn't surprising that he has already struggled to live up to the expectations put on him with his new team, the Indianapolis Colts.Early returns from camp have been poor when it comes to Heyward-Bey. He's been playing with the first unit as the #2 receiver, but he hasn't been the second best receiver on the field.One of the issues that he has been plagued with his entire career is a high drop percentage. That doesn't look like it's changing anytime soon.According to Derek Schultz, a local radio figure, Heyward-Bey has already dropped five passes through two days. Although the sample size is very small, it's a major concern because Darrius is having the same issues that he's been known for.Despite practices being without pads, this is a cause for concern if Heyward-Bey does not improve. Catching a football without pads is easier than catching with pads, so struggling now just looks bad, especially given his history.If this were Reggie Wayne, it would be much easier to overlook this fact. With Heyward-Bey, dropping easy passes in a no-pads practice is inexcusable and could really hurt the amount of playing time he gets once the season starts.The pressure for playing time is increased even more when looking at how well the receivers behind Darrius have been practicing. T.Y. Hilton has been playing very well so far, making great catches while using his speed to beat the secondary. Hilton also struggled with drops last year as a rookie, but we won't know how much he has improved until the pads come on and the catching difficulty escalates a couple of notches.Another receiver who has done very well so far is Griff Whalen. Griff has to feel very comfortable this season. He's catching passes from his college quarterback while being coached by his college offensive coordinator. He has shown off some impressive catches as well as running some great routes to gain separation from the defense. Although Whalen isn't going to be passing Heyward-Bey on the depth chart anytime soon, his strong performance early in training camp is promising for those hoping he makes the roster. The NFL sees overreactions from fans and media on a daily basis, and this is likely just another camp note that will mean nothing once the season started. With that said, though, Heyward-Bey dropped an easy pass over the middle of the field that hit him right in the hands with no defender around him. If he's struggling to make easy catches now, especially given his history of drops, it's definitely a cause for concern for the Colts and their fans. The Indianapolis Colts signed Heyward-Bey to a one-year deal in the offseason after he spent the first four years of his career as a member of the Oakland Raiders. When the Raiders picked him with the 7th pick in the 2009 draft, everybody knew it was a reach. Despite this, he was given high expectations that he never lived up to.One of the many excuses given to Heyward-Bey's struggles prior to this season has been the lack of continuity in Oakland, as well as poor quarterback play. Learning yet another offense means that only the improved quarterback play should be looked at for a reason why Heyward-Bey should improve this season. Based on the first impressions in training camp, though, Heyward-Bey still has a long way to go if he ever wants to reach the expectations he has been given.
