So you want to add an ace? Top targets and red flags

The best thing about the offseason: Every move feels big at the time, gets the juices flowing if it’s your team that made the move, and makes you start dreaming of April. Then sometimes your $126 million free agent makes eight starts and wins one game.

Anyway, you want your team to add an ace this winter? Here are my top five free-agent starters and the top five trade candidates who appear to be potentially on the block. Warning: I’ve provided the red flags for each pitcher. Buyer beware.
