The Tampa Bay Buccaneers' first four picks in the 2015 draft produced players who combined to make 57 starts in their shared rookie season. Even Buccaneers Head Coach Dirk Koetter, who last year relied heavily on three of those rookies in his role as offensive coordinator, knows that is an unrealistic expectation from any particular draft.
In the long run, however, that is the goal of every draft, to find players who will eventually develop into starters, forming the core of your team. That's what "build through the draft" means. Tampa Bay's 1997 draft produced a combined 28 starts in that first season, almost all of them by first-round picks Warrick Dunn and Reidel Anthony.
