Another wtf is going on here spots...preflop this time

Playing 16 tables i saw the dead money and thought it was an easy call preflop.
Sb is a good winning player which makes me suspicious of what he is doing preflop. The rest dont need expalanations, they're all short

$0.5/$1 No Limit Holdem
7 players
Converted at weaktight.com

Stacks:
UTG ($134.35)
Hero ($123.85)
MP ($47.25)
CO ($17.55)
BTN ($27.25)
SB ($138.05)
BB ($26.70)

Pre-flop: ($1.5, 7 players) Hero is UTG+1
BTN says "lol", UTG calls $1, BTN says "lololol 74 pre flop", Hero raises to $4, 1 fold, CO goes all-in $17.55, 1 fold, SB calls $17.05, BB calls $16.55, UTG folds, Hero calls $13.55

Not sure what you're asking here. Seems like a decent call for set odds, if SB wasn't in it you might even just raise and get BB AI too.

Is there a question here I'm not seeing?
