Since you are only going to get resources for 6, you may as well only recruit 6.
I would cut Harris, Burley, Lowe & Lipe this year. I would recruit a full starting 5 with one high-potential guy to redshirt. Keep the juniors, Lange and Preston for backups. Lange and Preston are barely above worthless, but they are slightly better than a walk-on. You can cut them next year to ensure you have 6 schollies and full money available for recruiting in your second season.
Next year, graduate the four juniors, cut Lange and Preston. Again, recruit a starting 5 and redshirt a high-potential backup.
Then your third season, you have an all-sophomore starting 5, with your freshmen 5 (+ 1 redshirt frosh) backing them up. By the time you have all juniors and seniors, your team will be *really* good.
