Boston Red Sox
As is, they are just as good as the Yankees right now but come at about $50 million per year cheaper. That's five Evan Longorias or three Jose Bautistas or two Pujols and a partridge in a pear tree. They have the money to spend if they see they are slipping.
Toronto Blue Jays
They are only one to two impact players away from being a division contender, and they have the money to do it as well. The possible $140-150 million payroll means $60 million they could spend on a needed player. They probably won't, though, as they have one of the best farm systems around, and their young core is in place for four or five more years.
Tampa Bay Rays
They have Andrew Friedman and Joe Maddon. They can make anything work, even a $40 million payroll to contend.
