It doesn't matter if she picked up a hair belonging to one or more of the team captains because none of them are whom she identified from the photo line-up. The thing to worry about is the search of Collin's and Reade's dorm rooms. Presumably the lab already had all samples before that, but I am champing at the bit to examine the chain of custody of the DNA samples and the rape kit swabs and combings.
The other players frequently spent the night at that Frat-house, so it wouldn't be just the DNA of the captains.
Early on the investigation when the reported the neighbor's complaints of noise, partying, urination... etc one said they have way too many people in that house - it violates some rule. Speculation was that the players sleeping over a lot made it seem like there was many players living there. 3 were on the lease, but 610 Buchanan was the hang out for the team.
