An important thing to remember with regard to the Mets starting pitching heading into the 2016 season: this rotation is still very inexperienced on the Major league level.
Matt Harvey and Zack Wheeler both pitched parts of 2 seasons (albeit large parts) before succumbing to Tommy John surgery. Harvey is only one season into his post surgery career and Wheeler isn’t even scheduled to return to game action until July. Jacob DeGrom has been great but is coming off his first full season. Noah Syndergaard and Steven Matz are both headed into their first full season. Bartolo Colon has a wealth of experience but the rest of this rotation will still be learning about themselves throughout the season.
Last season was great for all of these pitches (except, of course, for Wheeler) and is certainly reason to be excited and optimistic for 2016. And the Mets seem to be optimistic enough about their prospects for success this season to bring back Yoenis Cespedes to start the season instead of waiting for the trade deadline to see if it’s worth it to bring in a big bat.
There’s reason to be optimistic but let’s not get over confident.
