You have two options:
1. Go all in, find 5 guys you can start for 4 years. Watch them grow and dominate as JR/SR.
2. Go slow and steady, sign three guys, RS the best one and eat the walkons year one. Then sign 3 more, RS the best one, and eat the walkons year 2. Keep doing that and you got yourself a team in no time.
I would only RS, PGs and scorers. Someone with a 50+ WE and green in LP or PER if possible.
If you go route 1, don't worry so much about WE. Since the guys are going to start 110 games, it'll go up.
Plan your classes, make sure you always have a PG, for my money it's the hardest position to recruit and the most important player.
