For the purposes of this blog, one of the comments was quite pertinent, and very funny in the bargain. Andrew Luck is probably about three or four inches taller than Johnny Manziel, in case you aren't familiar with the two players in question.
July 9, 2014 Ted, the commenter, gave his opinion of the differences between Andrew Luck and Johnny Manziel: "About 2 feet in height, and that's just for starters! Johnny Football will be a BUST of epic proportions!"
Given that a bust can mean a sculpture, the comment could mean that Johnny will have a bust in Canton (where the Pro Football Hall of Fame resides) commemorating his Hall of Fame career, though I suspect not. Anyway, I think the comment is a nice juxtaposition of pointing out Manziel's relatively small stature (he's actually about six feet tall, so we're not talking about a small person here), with claiming he will be will be a huge football bust (that is, a big disappointment, of gargantuan size).
Tell us what you think, either about the pun or about Johnny Football. Heck, every other internet page has debated his merits or lack thereof!
