DL body types for 3-3,3-5

We are a small private school playing in AA (4A being the largest).

DE - 6-1, 225
DE 5-11, 190

NG 5-10 200

Our NG made 100 tackles and the larger of our DE was a good player who we put to the TE side. The other DE had never played the game and averaged 1 tackle per game. All of them could run.

I haven't run the defense yet, I will put it in this spring. I just started researching it in November after watching Tulsa play Boise State pretty tough. Last year I did run a 5-3 and my nose guard was 5'7" 165. He was all over the place. He had 11 tackles for a loss and had 80 total tackles. He is also a wrestler for me and had extremely good quickness, pad level and balance. It helped him tremendously. I do understand that the nose is put in a different situation in the 3-3 though. My nose was a senior so I'm moving my DE/OLB from last year to the nose. He's 5'10" 190. He's very tough and also a good wrestler ( I really believe that this helps my interior lineman a lot). I think he will do well for me. My Ends are still up in the air. I have a kid that played End last year that is 6'4" 205. I think he will do fine, he's just not as strong and doesn't have the pad level I would like to see with him. Can this potentialy hurt me out there? Are the things he will face similar to being a 50 End-- reach, downblock/ kick-out/ etc?

Coach,
We paly lb type of kids. Ends 180-220. Nose 200-240 more of a d-lineman type.
