I watched lots of early Whalers games on ye olde New England Sports channel.
Rogers was unquestionably a talented guy. Despite being a mediocre team, Hartford was offensively fun to watch with Rogers, Stoughton, and the still sometimes left wing Mark Howe.
Rogers was also classic WHA in that he signed with Edmonton where he could play play right away instead of going to Vancouver which owned his NHL rights.
The fact that Rogers scored 100 in his first 3 NHL seasons despite playing on a mediocre team speaks to his talent.
Being a star on a non-contending team, however, can be easier than being a star where expectations are higher.
After drafting Ron Francis, Hartford basically gave him away to the NYR for Doug Sulliman, Chris Kotsopoulis and a minor leaguer. They obviously felt that Rogers wasn't the type to build a team around and had more faith in an 18 year old Francis.
