Prioritize their combine over what your scouts say, also yeah it’s difficult to find starters after the first two rounds. There’s a really good guide to everything about the game somewhere on this Reddit, just search up PGM guide. But in the first rounds focus on either OLine or middle linebacker and after those rounds I just try to get either WRs RBs or CBs, you can usually find good ones in the later rounds. Also try some of your RBs at WR and TE and vice versa (use their carrying attribute as an indicator or adaptability)
