Always do the scouting combine first. Then you need to keep your cards close to your chest because others from your league may read what you write. (I was happy to blab last season because I had the first pick and it was a pathetic draft.)
Sort the players. Drag all the 18 year olds to the top and all 19 year olds to the bottom. If you want guards order then from shorters to tallest, if you want big men vise versa.
You wont have many points to spend. I suggest spend $20,000 a week. That will give you roughly 15 more points to scout about up to a dozen more guys. Then with your last 4, 6 or 8 points check the potential of the top candidates. Anyone with low potential just drag to the bottom of the list.
I would suggest you sit on your points until later in the season but I understand if you can't wait.
