Depending on how you calculate these things, Connor Lade is either the longest-tenured player in the current New York Red Bulls squad, or second on the list of longest-serving players on the roster. He was signed to the team in December, 2011, but didn’t make his debut for the first team until April 14, 2012. Ryan Meara (drafted by RBNY in February, 2012) made his debut for RBNY about a month earlier.
Despite his length of service, Lade has made only 88 appearances for RBNY in all competitions - and 30 of those were in his rookie season.
