There is one flaw in your argument . Kurt Warner was a very good QB and is in the Hall of Fame .
Cam was at best an average QB who , barring some type of major career resurgence, will never sniff the Hall of Fame. Check out his career stats. For his career, he has less than 60% completion percentage and QB rating of only 86.1. Compare these mediocre numbers to QBs like Rodgers , Wilson , Brady who have career completion percentages well north of 60% and QB ratings in high 90s low 100s. Even in his "MVP "season in 2015, Cam was not the best QB in the NFL as other QBs including Carson Palmer performed much better... People don't give enough credit to the Carolina defense which was something like no 6 overall during that season . Offense was not even in top 10. So to me saying that Cam carried the team raises a few eyebrows.
