Looking at some of the recent big pitching contracts that have happened, it's hard to predict who will be a disaster and who will work out ok. But a few things are generally pluses. First, if you have a history of being good, you'll probably remain good (until you suck). But the second big issue was durability. Pitchers who can throw innings, year after year, are a safer bet than those who didn't. The third main plus was age - the younger, the better. So I would think Lynn is the safest bet of all these guys. He's not an ace but he could be another Ervin Santana type. A guy who, in his best seasons, could be an all-star.
