Will tanking mmr in normals make ranked easier?

I ran into this player who didn't say a single word today from champ select to the end of the game, they're currently 0/2 on promos. Will Lowering your mmr make it so your opponents in ranked are worse? http://na.op.gg/summoner/userName=CJKA1 <-- Link to the summoner http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1806702714/218686320?tab=overview <--- Link to the direct match

I guess if you're that bad you shouldn't be past bronze 5
