oh? you want an argument?
i spent many-a-year watching my team nickel and dime the fanbase, cry poor; and i prayed to the Good Lord Almighty that one day the owners of my favorite baseball club would have it in them to actually spend for quality players - or more aptly, to spend to retain homegrown talent.
there ought not be a cap in baseball b/c it's restrictive, penalizes the teams that have a dedication to winning, and quite fankly, it's anti-american. why should a team like the yankees or boston be saddled w/ a spending limit when all they are trying to do is to win? i mean, think about that for a minute...fans cry when their team's owners don't pony up. they pocket all the revenues from new stadiums, all of the merchandise, concessions, etc. however, when it comes time to reinvest, they divest. so to whine about a cap is often hypocritical imo. don't even tell me that if your beloved indians threw $180M at sabathia last summer that you'd be complaining...you'd be here on the boards talking about how he was going to win multiple cy youngs and carry the tribe into october
as for the red sox not having any ideological leg to stand on...if it's texiera you're referring to, big deal! the sox will be just fine w/out texiera! they're solid already. sure he'd have juiced up the middle of that lineup and maybe would have given papi some extra protection. but that kid they got from the pirates did pretty good imo. so if i were a red sox fan, i wouldn't worry. there's enough of a nucleus in place already.
re small market teams - sure, they're at a disadvantage in terms of payroll. but that is just a different tact. teams like that often focus on developing their minor leagues and spending what money they have on scouting, etc. as we've seen over the last decade or so, this strategy often works. paying the players once they become eligible for free agency is another matter. but the shrewd gm's often spin these guys off for some pretty nice packages at the trade deadlines. there are also the teams that have both the cash to spend on FAs and to dump into their minor league development (ie boston). this, imho, is the pinnacle of a successful franchise (championships notwithstanding).
sure, they yankees have made the playoffs all those years. but were they ever poised to win it all outside of maybe '04 before the collapse (and '01 but the d-backs were an anomoly that year)? all we've heard over the last few years has been a-rod's oct choking; and the tide has turned against them w/ the red sox. they pretty much have had the yankees' number ever since that epic collapse. add the rays into the mix and it there's even more obstacles for the yankees.
btw, burnett is not a roll player. he led the al in Ks last year and when healthy, he has an electric arm. on paper, he is quite a boost to the yankees rotation.
