I obviously did this wrong before training camp. I moved my drafted C to LG before training camp hoping to get him to boost there instead of C because I have a good C already. Sadly it didnt have him as LG which now kinda kills me.

Is there an official way to move someone to a position to avoid messing up your training camp and draft?

On the players profile you can change the position. There should be a red button "Change Pos/#" (or something similar)

ahh ok cool I found it. So my question now isif i move him how will it effect his improvement as a player? HEs a 50/84 Center now. If I move him to a OT/OG position it could drop from to about 37-43 overall with an 80 future rating. He gained +9/+2 from training camp. Would the move even be worth it because of the big overall gap ATM or should I just draft new OL and learn from this mistake?

the only difference is weight, his short snap and strength should be fine. You can move guys around on the line however you want and they should progress very similarly. A center will trend towards 283 lb's whereas a guard will go upwards of 316. The overall rating is not a big deal, just make sure you keep tabs on his blocking skills as he progresses
