It may be a stretch but I think the Reds may have a net positive by the Red Sox signing of Matsuzaka. Here's my theory: Bronson is pining for Boston, but he has two more years left in Cincy. In two years, the Sox will have at least Matsuzaka, Beckett, Papelbon (arb-eligible) and Lester under their control. If Schilling retires after '07 they will try to replace him before '09 (when they could resign Bronson). Thus, Bronson's timing and Boston's need may not be compatable, making it easier for him to stay in Cincy.
Of course, he could devolve so much by then from his 2006 season that neither team will want him. But I'm thinking positive--and this I believe is a positive sign for the Redlegs.
