Why I Just Called on the River

I was in a hand in a NL home cash game last night where one player chided me for not raising on the river.

The Hand
In early position I raise to $3 with 7-8, get re-raised to $8 and call along with one other player. Three players and $25 to the flop. Flop comes out Kd-Jc-7d. Check-check [me]-check. Turn is a 2c. Check-check [me]-check. River is a 7h. $25 bet from player in bb, I call, last player thinks and complains and calls too. My trip sevens are the best hand against the last player's J (bb was on a steal) and I take the $100 pot.

Why I Just Called
When the bb bets out on the river after two checks, I knew they were on a steal, so there was no point in raising them. I also know that the only way I'm getting re-raised (if I were to raise the $25 bet to $75 or so) is if the last player had some sort of monster like pocket J-J for a full house or something like that. It doesn't make sense in this scenario that the last player has any King or better hand based on two checks on an otherwise dangerous board. Since I can't get any more out of the bb, the only way I am getting anything out of the third opponent is to smooth call and hope they think I'm calling with Ace high or something (perhaps even two pair with a low pocket pair) and hope they do in fact have a Jack they think could be good, which is exactly what happened. If I raise, I am only getting re-raised by a better hand most likely (although it would be quite odd for a player to have slow played a set all the way to the river on this board, so I would have a decision to make there), and I also figured the $100 pot is enough for me getting lucky on the river.
