It didn't take long for Theo Epstein to get another offer to be a baseball general manager -- if he doesn't mind cuts in his salary and the team payroll. The independent Brockton Rox, who play about 30 minutes south of Fenway Park, offered Epstein their GM job on Thursday. The team, which plays in the Canadian-American League, is restricted to a total player payroll of $87,500 -- far less than the major league minimum of $316,000 per player and far below Boston's $126.8 million payroll this year. ``It's assumed that Epstein is looking for a greater challenge,'' the team said in a statement, noting that Epstein could sweeten the pot for players with an $18 per diem and put them up with a host family.
