I agree with all of this.
English can and should be a very good ruck, even his timidness should not be an issue in a few years. By biggest query on him is that he is not a natural hitout guy, so I doubt he ever truly becomes an above average tap out ruck, but his around the ground work should more than make up for that.
Naughton stays forward, as said above he could be the best in the game. If we need a lock down defender then the past has proven that they don't need to be amazing. They can be found with late draft picks and rookie spots, dominant key forwards cannot.
