Our reading
An editorial interpretation.
The speaker praises Lloyd by distinguishing being good from being great. Calling themselves good provides a point of comparison that makes the compliment stronger. The repetition places special emphasis on Lloyd's character, presenting him as exceptional rather than merely decent.
