Never retire, but I hear ya, I get frustrated, too. There are still things I just dont understand about Buzzerbeater, and that's why I cannot make any progress. I seem to be capped out and treading water. I often have to restrain myself from blowing it all up almost every week, but in the past, when I've done that, I've regretted it.
So! To another draft we go. Here's to another year of hoping I'm learning something, but ultimately I'll be in 4th place once again, wasting all my cash and mismanaging my minutes.
