The tournament structure just makes that tough. Using Chandler as an example: He just defended his belt at the beginning of the season. The LW tournament started 2 weeks later. Because tournaments take 3 mos to complete and the winner will need at least 3 mos to prepare for the shot...Chandler wont likely fight again until summer.
One good thing that Bellator has done is somewhat stack the tournament winners. The last LW tournament final had to be postponed last season and will happen in 2 weeks. That means that Chandler will have potentially 2 opponents waiting for him next season.
