the survivor producers deliberately put weaker people on the malolo tribe so that their favourite castaways(Wendell,Domenick,Kellyn,Chris,Desiree,Sebastian etc) that they wanted in the end or atleast merge could go far
cause i mean if you look at the Malolo tribe
Jacob-could do nothing but find idols cause he knew he was weak
Gonzalez- weak
Jenna-Weak
Donthan - weak
Brendan- strong but was not as tall and big like the naviti guys
Libby - she was okay
Laurel - she was strong but you only as strong as your weakest link
James - oh well he let the team down but he tried in some challenges
Stephanie- same as Laurel
Michael- Strongest male in the tribe but i mean if your team is weak what can you do...nothing
in conclusion: Malolo tried but didnt suceed. and Laurel defintely wont win.
