I didn't think Chaplow was that bad - I think injury just let him down as it does with quite a lot of players who played for PNE. Chaplow also scored twice as many goals as Carter as well in a lot less appearances.
The other thing you can compare as well is the clubs they signed for after they left PNE. Chaplow made quite a few appearances for Southampton, Ipswich and Millwall as soon as he left us, whilst Carter played for Cheltenham, Northampton and Forrest Green. I think that shows which player had the most effort and better attitude.
