Let's see you have a "short" chance to make millions of dollars and develop into a player for 8 years.. do I sit at home with my "gf" or do I take advantage of a opportunity that less than .05% of people have..
Hmm... I think that's an easy answer
I dunno Silvr, players are human, too.
Some of them have wife and kids (even some rookies.)
For the rookies, it had been a long season.
They spent a lot of time the previous training to get ready for the combine and/or their work-out before the draft. Some have many private work-outs in different cities all across the country (lot of traveling.) In a normal year, the OTA follows shortly and their schedule never really stopped until the end of the play-offs (for those whose teams made it that far.)
This is the first real chance for them to have a little time off.
Besides, according to the new CBA:
Prior to the commencement of the Club's official offseason workout
program:
... (ii) play*ers are not permitted to participate in Club-supervised workouts, Club-supervised
practices, group or individual meetings with coaches, group or individual film study with
coaches, or group or individual playbook study with coaches;
... and (iv) play*ers' activities may not be directed or supervised by any coaches.
.....
There's not much difference staying or going home for a short while.
And I would say time-off for reflection is always beneficial, but that's just me.
