I'd hardly blame Uconn for dropping the ball... When is a game schedule released for the upcoming year? In the summer correct? So Syracuse posts their schedule two years in advance? Unlikely... Concessions are made all the time... Maryland agreed to play in the Maggie Dixon Classic at the last minute... So it comes down to willingness...
It's a good thing they didn't line up a home game for DeJanae Boykin, or Sadie Edwards for that matter. I'm pretty sure it's SOP to wait until Senior Year to line up these games.
There is a huge difference between scheduling the exact date of games and scheduling a series with a school. Uconn has scheduled Baylor for a game in the 2016-17 season somewhere in CT at some time, and a return game I believe in the 2018-19 season at Baylor three years out. We have a two year contract with TX, and I believe a four year one with one of the other schools. The conference schedule isn't worked out until August usually so they cannot 'publish' a schedule until that is completed - and most schools use the same facility for MBB, WBB, and often other sports and other non-sporting events.
It is completely understandable if Syracuse or any other program has committed to 'x' number of OOC games two years in advance - they may have a few available slots still to be filled 16-18 months in advance, and even 6 months in advance they may be filling in a slot - but by that time there may only be a few available dates into which they can schedule a team and matching those dates with another program that also has only a few windows in their schedule may be an issue.
Specific to this year - Uconn actually screwed up in their scheduling because they had committed to too many games (28) to be able to schedule an in-season tournament - they actually went back to a couple of schools they had scheduled to see if they could defer that scheduled game a year, or alternatively get that school to change the game to a tournament that they would both go to - none of the schools were able to accommodate that change so this year we are playing 38 games (they added another single game to the regular season to get up to 29) instead of what has become typical, a 30 or 31 game regular season and with post season runs a 39 or 40 game season.
