Biggest Strength: Low-cost power source.
Ross had to settle for a one-year, three-million deal with the Red Sox last offseason, and he far exceeded expectations with a .267 BA, 22 HR, 81 RBI season, hitting in the middle of the Boston order. While he'll earn a raise over that three-million salary, Ross may still be the best cheap source of power on the market.
Biggest Weakness: Inconsistent.
After putting together a .270 BA, 24 HR, 90 RBI season in 2009 with the Marlins, Ross struggled to the point of being designated for assignment the following season. The Giants picked him up, and he turned out to be a major contributor during their title run, earning a $6.3 million salary for 2011. However, he followed up his postseason heroics by hitting just .240, and as a result, he had to settle for a low salary last season. To put it simply, you just don't know what you're getting with Ross at this point.
