In a meek defense of Ryan, let's just say that it's his job to take an opinion and speak of it as if it were fact. That is what columnists do. They aspire (often) to be controversial; they say/write things designed to provoke people to talk about it at the proverbial water cooler. Don't you love to hate Steven A. Smith because he states opinion as fact? That's his job.
When writers and talking heads provide 'expert' analysis on games that have already been played, they at least can point to actual situations that occured on the court and comment (you can then retort with factual data to rebut). But, when these same folks are talking about what has yet to happen, they have the unenviable task of being the supposed 'expert' discussing something that is so speculative that if they are correct 51% of the time, they probably should consider themselves very lucky.
Bob Ryan took a provocative stand on something that no one KNEW was going to turn out as it did. Yes, many of you THOUGHT it would turn out well (perhaps not this well). But rather than getting too full of yourselves, perhaps you can chalk your correct guess about the C's fortunes alongside all the one's you've missed (you know, the scrap heap littered with 'Kedrick Brown/Gerald Green is gonna be great' and 'Doc can't coach them out of the second round' and 'Wyc won't spend the money',....), and cut Bobby a touch of slack.
