My thinking behind it is a couple of things. I may have enough going into next week with 7 trades to go straight to Mitchell to Teddy in 1 trade. If I kept SST he'd probably lose money whereas ET should hit his BE even go past it. If I need an extra 10K to fund the Mitchell to Teddy trade, I'm thinking about doing a sideways trade of ET to someone like Finucane to get a solid backup player while getting Ted in my 17. Keeping ET over SST should give me more options of a worthwhile sideways trade.
Also, I think ET could have a big game. He's a new recruit that puts in the hard yards and want to keep his spot. With the Farrah shit, perhaps some of the squad will feel a bit dejected and ET not having any ties with the history of the club could pick up the slack if the rest don't pull their weight due to this.
