Boston doesn't rush their young players, that's an "urban myth" - like most teams, some start early, some need time:
Pastrnak #25, playing at 18, full-time at 20
Carlo D #37, starter at 20
MacAvoy D #14, starter at 20
DeBrusk #14, starter at 21, at 22 [40g, ES 9-3 12]
Krug D, UDFA out of college, starter at 22
Grzelcyk D #85, starter at 24
Kuraly, #133 (SJ), acquired in Martin Jones trade, starter at 25
These guys are starting, but aren't playing better than Weal [28g 3-4 7] or Weise [42g 4-6 10]
They reflect Boston's lack of depth at forward.
Heinen #116, starter at 22, at 23 [47g 5-5 10]
Donato #56, starting at 22, [34g 3-3 6]
JFK #45, starting at 22 [28g 3-5 8]

Patrick #2, starter at 19
Provorov D, #7, starter at 19
