I saw a twitter mention or blog entry from one of the blowhards that said Gilmore might have been targeted because, after his signing with the Patriots, he said he 'finally would be on national TV' (or something like that). When he said it, it apparently made a few rounds in the Buff sports media circles as a knock on the Bills as well as Buffalo. So the suggestion was there's been hard feelings about it and that would explain why Gilmore was repeatedly targeted on that series.
Probably a steaming pile of BS but I did think it odd that the Bills would do back to back (to back?) throws at Gilmore.
