#6. Matt LeBlanc
You would think that Matt LeBlanc was The One With the Most Potential, because after all, it is LeBlanc that was gifted a Friends spin-off by NBC; a should-be success with a built-in fanbase of millions.
Too bad that Joey was pretty much unwatchable, even for the most die-hard of Friends fans (I gave it about 5 episodes before determining it to be a lost cause). Somehow though, Joey survived 2 seasons and 47 episodes.
And since Joey? Check out Matt LeBlanc's IMDb credits. Holy crap! Matt LeBlanc has not even starred in any C-rate TV movies. Joey is LeBlanc's sole post-Friends credit (though he is supposedly working "behind the camera" now).
Depends which image you look at (and there aren't too many current ones to choose from).
The image on the left is from circa 2006, and not to be mean, but I can see why LeBlanc is working behind the camera now. Yikes! However, in the image on the right, though LeBlanc looks decidedly old, he doesn't look half bad (minus the cancer stick), and might rank above a few yet to be named Friends castmembers.
Since these two images are drastically different (and what LeBlanc looks like in 2008 is a mystery), we'll have to settle for a "Maybe" in answering the above question.
So, with a definitive "No" for both onscreen and offscreen success and only a "Maybe" for "Hotness Retained", Matt LeBlanc earns himself the #6 slot in our Friends: Where Are They Now (in order of success) Feature.
On to the #5 selection: Matthew Perry
