My simple to-the-point 2 ¢:
If you’re drafting for the joy of a HG team, then it’s totally worth it, enjoy the fun.
If you’re drafting for a good training prospect (up to a MVP), it’s way easier and probably cheaper to find one in the flood of rookies on the TL in the first week or so.
If you’re drafting for a great / NT prospect, you’ll need to hit in the draft or have a boat load of cash for the TL. Good luck.
If you’re drafting to make money on the TL, don’t. It’s like playing the lottery: You may get lucky, but probably not.
