Yes there is an identity - it's called "soff".
Pretty much. I'm honestly fine with each player individually, but the combo just blows.
Spaling - solid positional player, good defensively, decent along the boards and can score the random garbage goal but pretty much devoid of creativity or actual offensive skill (or at least he doesn't to anything remotely creative or risky with the puck on his blade).
Sutter - solid positional player, good defensively, nice shot when in open space off the rush, soff as hell, sucks in board battles.
Bennett - good playmaker, crafty, meh skater but decent edge work, fairly soff, poor release on shot (decent shot when in open space, can pick a corner)
All 3 are prone to disappearing acts. I'm really not sold on the Sutter-Bennett chemistry thing, but if that is a combo they still like, they need to find a different type of player than Spaling to compliment them.
Take those descriptions and add their cap hits alongside them and it's clear we are spending far too much on that line for the type of role or production we can expect from them.
