What it tells me is that pro ballplayers have a code of etiquette not to make announcements during the playoffs that can wait for the offseason.
Tom Brady has Patriot fans on tenterhooks as well and I expect it's for the exact same reason. Right now the football world is focused on the 49ers and Chiefs and it's considered really bad form to drop news bombshells during that time that distract from those 2 teams, especially if it can wait a week or 2.
Also agents do't like to release news in that time window either because it's easier to get buried in Superbowl news which doesn't give their client the attention they fee they deserve
Within about 2 weeks of the end of the Superbowl a lot of metaphorical shoes are going to drop at once. Lots of players and teams are biding their time right now and things aren't getting out unless there's a leak in the FO or agency in question
