If Kevin Towers had taken Boston's GM job, there was an excellent chance he could have persuaded David Wells to stay in Boston. Towers and Wells are very good friends, from Wells's time in San Diego. Towers, who wants to remain San Diego's GM even with Sandy Alderson above him, may soon try to work out a deal to reacquire Wells. It was no secret that Theo Epstein liked Padres righthander Brian Lawrence, but Towers recently shipped him off to Arizona, where Epstein's former assistant, Josh Byrnes, is now the GM and apparently shared Epstein's opinion on Lawrence. There has been some discussion about former Sox outfielder Dave Roberts returning to Boston, along with a pitcher, for Wells.
