I wouldn't dismiss the idea...

...of him returning under a one-year deal. A LOT of veterans will be signing one-year deals this spring (by choice or not) due to the lower cap. It will be interesting to see what the market is or is not for him. It is definitely a position that could be upgraded. At the same time you can't categorize Blythe as a 'liability.' Maybe they go try and get an Alex Mack or similar while drafting a center. But could Blythe be back with a 3rd round pick center drafted? Could happen...
