Are these stats possible?

A recently added friend of mine has some interesting stats, and I was wondering if they are possible…

Campaign - Legendary complete with only 225 kills. He did it co-op but did he seriously not help at all?

Spartan Ops - only 1 kill, no matches complete

Multiplayer - I forget what rank he is, but he is wearing the Engineer body so I would imagine he is at least in the 50’s. Anyway, he only has 200-300 games complete and around 2500 kills and 3100 deaths.

So is it possible to be in the 50’s or possibly higher with stats like these. The only way I could see this as possible is if he used double xp a lot or won almost all of his games?

I could just be overreacting, but I think i wasnt in the 50’s until I had around 4000+ kills in war games, and this was with a decent amount of Spartan Ops games played with double xp.

Your thoughts? I could be wrong… maybe he is just a really good player…

The only thing I think is strange is the amount of kills and deaths your friend has. It sounds like he is a booster, though I could be wrong. He may just be a good player like you said.

I just confirmed that he is level 56…

He may just not have chosen a specialization at level 50, therefore he has many kills, but he is a low rank.
