Its all about the money. Most of these players only care about winning AFTER they have inherited millions of dollars. Ric is dead on about this point. Another example would be Jon Runyan leaving the Tennessee Oilers for the Eagles (When they sucked). I only point this out because it pissed me off at the time. Money talks.
I have to agree with you... The Texans are on a 3 year building plan anyway, and while a guy like Boston could seriously help the passing game, we're probably better off drafting a Charlie Rogers or Roy Williams instead. However, if Takeo Spikes is available in the off-season, can you imagine the possibilities of having him and Sharper up the middle? Boy, wouldn't that be sick?
"nobody as big boselli" may very well be the understatement of the year; here's a quote from the article you linked: "As expected, Cleveland avoided high-priced players like Denver's Darrien Gordon and Washington's Gus Frerotte, opting instead to take players it considers to have long-term potential while saving money to use on free agents." they passed on gordon and frerotte?!?!?!?!?! the high-priced talent in houston's draft has actually, at one point, earned its high price. boselli, glenn, coleman, lewis, sharper and walker (the highest of the high priced) are all light years better than gordon and frerotte and anyone else available in cleveland's draft. cleveland would not have passed on that kind of available talent. also, it should be noted, houston passed on quite a bit of high-priced talent, too. rob johnson was available; romanowski; rob moore... it's not like the texans loaded up on overpaid has-beens.
