Folding 22 OTB to 100BBs after limping in a multi-way pot PF

[Phyreball]

So, I was watching one of 2Paul2's 4-tabling 100max tables, he has 22 OTB and limps after 2 limpers. SB (100BB) raises to $5, folds to him and he folds. With no reads, would you make this fold as well? I feel like I would've made the call because I feel I have the implied odds to stack him like I do with any other pp. I don't think I'd ever fold any pocket pair OTB to 100BBs without reads. Is this a leak?
