First, the Panthers went to the SB five years ago. You know who else got MVP votes that year? Carson Palmer. Cam having a good year five years ago is irrelevant.
Second, Cam's efficiency and ability to get wins in 2015 was pretty much an outlier year.
Because QBs being physically similar is all that matters when it comes to in game performance...
Cam and Luck had a lot of similarities in the way they played QB. Also a lot of differences. Anyone who watched them play knows this.
I'm not sure what this comparison has to do with Rivers.
I also don't know why you're not acknowledging the clear issues that Cam has with playing QB in the NFL. Instead, you're acting like "MVP! #1 pick! Went to the SB!" means that there are no issues with the way he plays the position.
