The Aviva Premiership’s top try scorer doesn’t make the expanded Six Nations training squad despite crossing the whitewash eight times in the Premiership this season.
With injured duo Marland Yarde and Christian Wade unlikely to play a part in the championship, it leaves options on the wing such as the out-of-sorts Chris Ashton and the inexperienced Jonny May and Jack Nowell.
It's admirable to give youth a chance, but with the World Cup next year Lancaster has no clear picture of who will make his back three up.
Yarde and Wade would have been given their chance to establish themselves in this tournament, but the next men in the pecking order are now in the squad knowing they are far from Lancaster's first choices.
Strettle would bring an experienced head with a keen nose for the try line, but at the age of 30, he doesn't seem to fit the profile Lancaster is looking for.
