It's been a difficult start to Darrius Heyward-Bey's career in Oakland.
First, his selection at No. 7 in the draft was panned almost universally because he was taken ahead of fellow receiver Michael Crabtree.
Then, Heyward-Bey lived up to his college reputation for having suspect hands by dropping passes on three straight plays on the second day of Oakland's mandatory minicamp in May. Later that day, he suffered a hamstring injury.
Heyward-Bey then missed time because he couldn't participate in voluntary camps while his school, Maryland, was still in session.
He came back from a hamstring injury last week, but on Wednesday, on the second to last day of the OTAs in Oakland, Heyward-Bey hurt his hamstring and had to leave practice.
So, he heads to training camp with questions about injuries on top of everything else. The rough start, of course, doesn't mean Heyward-Bey is going to be a bust, but it is just a tough start for a player who needed this developmental time.
