Orchard Park, N.Y. — The Buffalo Bills are strapped for cash after a few weeks of aggressive spending in free agency, and that leaves the NFL Draft as the next step for adding talent to a roster that has already taken a big step forward this offseason.

At this point, the pro day circuit is winding down, and the Bills will have plenty of prospects coming through One Bills Drive over the next few weeks leading up to the draft on April 30. Each team is allowed 30 official visits before the NFL Draft, but Buffalo has also been tied to a long list of prospects throughout the process at the NFL Scouting Combine, all-star games and pro days.
