Cowboys don ' t turn the ball over . They also don ' t create turnovers . OverUnder for turnovers that game should have been . 5 <| sep |> There ' s certainly a better idea of how long it took now . Maybe after Rogue One we ' ll have an even more detailed timeline . maybe . But it ' s still unknown as to when the structure itself was completed sometime during those 19 some years between Ep III and IV compared with when the weapon was complete , which is what Rogue One and Ep IV are about . I think this theory of mine adds a nice helping of typical Palpatinedeviousness to the origin of the second Death Star . It makes it more intriguing at least to me by expanding its connection to the first Death Star ' s origin , beyond the simple explanation that they had experience building a Death Star , so when the first blew up they just built another , but this time , because they knew how to make the weapon , they made sure it was ready to roll long before the battle station itself was complete .
