Extending Jansen at a reasonable price gives the Blue Jays more flexibility, not less. You can easily trade him for even more return if that is needed. In an age where teams are paying Vazquez $30 over 3 years, and Hedges $5M for a year, it is easy to imagine how you can get premium returns for 3 years of Jansen at $12M a year. Extending Jansen also allows the Jays to have a safety net if Kirk becomes less productive for whatever reason.
