Sounds right. Red Sox probably had a best-and-final offer at 7/185 teed up, figuring it would put them over the top. It ended up that even their best offer wasn't competitive with SD's offer.My impression of things is that they felt they were still in the running with the 6/160, not that they thought it would get done at 6/160. Then the Padres came out of nowhere and way over the top with their offer and that's what left them shell-shocked.
I note that the Globe article didn't say that Bogaerts' thoughts on 6/140 and 5/151 were ever communicated to the Red Sox. I assume the 4/90 offer was simply rejected out of hand and never counteroffered. Then Bogaerts indicated they would not negotiate during the season, which effectively indicated that he was going to take the best offer once he became a free agent.
