Mickey Callaway might have a background as a pitching coach, but he's got bigger problems to worry about than just mechanics and bullpen sessions these days. Callaway and the Mets need to bring in a pitching coach to replace Dan Warthen, who was fired following the conclusion of the season and offered a front office role (which he has not accepted).

Several organizations just parted ways with their pitching coaches, but there's a catch: Many of them are old-school arm guys, not necessarily the new-school analytics guys the Mets seem to be targeting. But still, it's not a bad group from which to choose.

Neil Allen

Pros: The recently-fired Minnesota Twins coach is a curveball expert, having learned the grip from his blind father as a child. A former Met, he pitched for New York from 1979-1983. Allen's story is a great one of perseverance: A recovering alcoholic who lost his wife to an instantly fatal aneurysm at the age of 54, and to make matters worse, he was right next to her when it occurred. The Twins' staff improved in each of the last two seasons and they went from one of the worst teams in baseball to a Wild Card team this season.

Cons: He was let go by the Twins after the staff posted ERAs over 4.00 in each of his three seasons with the team. Also, he relapsed in 2016 and was charged with a DUI.

Chances: Allen's name could pop up since the Mets love to hire their own, but it seems unlikely at the moment.

Carl Willis

Pros: Willis coached three Cy Young Award winners during his time as the Mariners' and Indians' coach (CC Sabathia, Cliff Lee and Felix Hernandez) and the Red Sox had the fourth-best ERA in baseball under him this season (3.40).

Cons: The pitching fell apart in the postseason and Willis is still technically on staff in Boston, but until Alex Cora and Astros end their World Series run the state of their contracts are all in flux.

Chances: Willis is already interviewing with the Twins to replace Allen so it doesn't appear as though he's on the Mets' radar just yet.

Dave Righetti

Pros: Righetti's pitchers dominated baseball for six years and led the Giants to a three-championship dynasty. Tim Lincecum won two Cy Young Awards while working with Righetti and Madison Bumgarner knocked off the Mets in the NL Wild Card game last year. He was the Giants' pitching coach for 17 years and four World Series, so clearly he knows a little about pitching.

Cons: Righetti was fired because of his old school coaching style and it didn't mesh with the Giants' desire to expand their analytics applications.

Chances: Not happening, because Righetti has already taken a special assistant job with the San Francisco front office. But if he decided he wanted to be on the field instead of the office, he would be worth looking at.
