So, not specifically to your question first (and other coaches will probably disagree) but recruiting is not the most important aspect of the game when rebuilding. There I said it. Go ahead and yell at me everyone. Scheduling is more important. You have to find 10 sims you can beat on the road. To start I don't care how bad they are, although obviously you want the best you can beat. Wins increases prestige, at least indirectly, and you have to get your prestige up.
Next, I wouldn't play man to man. You will probably have weaker players than most humans for 4 - 6 seasons so trying to match your guys against theirs will often get you beat. Fast break press will give you a shot against better teams with short benches. Zone will let you play 8 - 9 guys and you can take ineligibles, who sometimes slip through the cracks, and guys with lots of potential who will redshirt, because you only need 8 guys. You can also intelligently gamble on guys because taking walkons is not the end of the world. Anyway, just my 2 cents.
To your question, the general overall idea is the same as all divisions. I don't recruit that differently from d1 to d3.
1. Take what the game gives you. Sometimes you really need that pg and there just isn't one you can reasonably get who is any good. But a pf has fallen through the cracks to you. Take the good pf, not a below average pg, and make the pg position work somehow. So after a few cycles look around and see who isn't being recruited that would help you and take a chance. Sometimes other schools notice them and you have a decision to make, but sometimes they don't, especially early signers, and you can sneak better talent than you maybe should be able to just because you're observant. Your goal in your first couple seasons will be to win the 23 sim games on your schedule if you schedule 10 nonconference, to increase prestige. You can do that by just out talenting them.
2. Be the bully, don't get bullied. Look at some of the d2 teams around you. All the good ones will have d1 level players. Your goal should be to be an all star d2 team early in your tenure. In most cases if you took the top 12 players on d2 teams within a 300 mile radius of vmi, you'd be a decent d1 team. So don't be afraid to battle the d2 team for a player that will help you beat the sims rather than the B prestige team who probably has you beat most of the time if the player is any good. Of course preferences and priority can give you a reasonable shot against higher prestige teams but you have to be smart and observant in your choices.
3. Worry about cores. For guards and wings at low level d1 you should want guys who will have a sum of 240 with athleticism, speed and defense after growth. In addition it would be nice if they can do one other thing like pass or shoot, but you won't always find that. In bigs athleticism and defense should sum to 160 after growth and it is nice if they can do one other thing, mainly rebound or score. You may not get both.
4. Offer starts and minutes. It's why I like fast break press for rebuilds, because you can offer starts to 5 guys a season and your true starters still play a bunch, just off the bench. This leads into #5,
5. Find guys you don't have to spend money on who can play for you. It goes back to being a bully. Offering a guy a start and minutes will often, not always, scare off the d2 teams. If you can get them for nothing then you can max resources in a couple battles that you feel you can win for guys that are at the next level.
6. And this one can be the toughest, don't fall in love too deeply and know when to let go. It's like when you date the girl way out of your league, enjoy it while it lasts because it probably won't last forever. It's great to lead for a day on the stud you should never get, but if mr. A+ comes around and you realize you have no chance it is better to cut bait earlier rather than later and find that next target.
Like it was mentioned above, there is more than one way to be successful, but have a plan and bring in talent and you'll do okay. To me the key is beating sims for a few seasons, and as your prestige goes up so should the level of player you should target in recruiting, which allows for more gambles because you'll have more of a shot with those gambles and you'll be able to secure the talent a tier down easier if you miss.
