Yak and RNH. RNH has been terribly underdeveloped and is only now starting to look close to as good as he was in his rookie season offensively. 2/4 first overall picks we've failed to turn into 1OA level players. 1/4 we've failed to even turn into a top 6 player. Meanwhile good organizations turn their late firsts into NHL-level players at a similar rate. It's pretty pathetic how bad the Oilers have been.
