Jordan Zimmermann can help Tigers, but deal is definitely a risky one

The Detroit Tigers came into the offseason with only three solid starters, one of whom, Daniel Norris, has just 66 career innings and had surgery in October to treat thyroid cancer, so adding a veteran starter capable of soaking up innings had to be a major priority for the winter. Jordan Zimmermann fills that specific need quite clearly, as he has been durable and effective since his return from Tommy John surgery in 2009, but a downturn in his stuff and performance in 2015 makes it seem the Tigers are paying for a version of Zimmermann that no longer exists.
