He says the Oswalt offer is about 5M, but Karl Ravitch has reported Oswalt is deciding between Texas and St. Louis. The Cards had offered a little less than 5M previously. As for Jackson, he thinks the offer is around 7M or 8M, but that both pitchers may be afraid of the AL East. He also indicated Cherington is willing to negotiate in a patient and conservative style.
He stupidly says the pitchers may be afraid to come to Boston because three of the top six offenses in baseball are in the AL East. Of course, Boston is one of the three and it is unlikely Boston pitchers will have to face Boston hitters too many times during the season!
Of course, the level of competition is high, but when you adjust the raw numbers for park and opponent strength, it should even out anyway. I think Oswalt is simply looking for a bigger offer and Jackson wants another year.
