It's an age old question I guess. Actually not, but it has become unanswerable.
to some degree.......i would have a hard time not believing that the popularity alone of the NFL outweighs its baseball counterpart these days.
i look at it like this......i'm a pretty avid sports fan, i think i keep up with things pretty well, and the only thing i could really tell you about MLB this year is that the Sox and Yanks are hte favs in the EAST, the Tigers are the fav in the Central and the A's are the fav in the West, that Kerry Wood and Mark Pryor are talent wasted cause of injury, that Tony Larusa had one too many and Barry bonds is going to break HA's record.
now, other than the Larusa story, how much of that has changed really over the last 3-5 years? there's virtually nothing new coming out of baseball, except where Roger Clemmons will pitch, if anywhere......
the same teams, largely, year in and year out, are the ones that gobble up all the story lines, there is a defnite line of demarcation drawn between small market and large market teams. those that don't spend, don't compete, generally speaking (i know the marlins beat the yankees).
there's just not much there to hold my interest......now, i will freely admit the Red Sox run in 03 was great, and i watched a lot of that. the Cubs run in 03 was great and i watched that. and i'd watch again if it were those teams involved.
but i certainly could not see myself getting all excited about a Royals/Brewers World Series---which will never happen anyway.
think about it....when you were a kid, did you ever think the Bucs or Patriots could win the Super Bowl? now they are regular contenders, and in the case of the pats, the new dynasty of this decade.
this goes all to competitiveness of the league, so i've strayed off course here, but it does play a part in the popularity of the sport.........and it does give credance to the mantra "there's always next year" in relation to football, where in baseball, it's largely a forgone conclusion....
