The simple fact is that Smith was on TMS yesterday pretty much saying that Jennings would tour so it is what it is. Apparently he is being interviewed by Atherton for sky this morning so that will be interesting to see.
I think they want a bit of continuatity as Cook is retiring and also think Jennings can play spin well. Which let's face it Sri Lanka will be bowling from pretty much ball 1 anyways.
Also I know Jennings hasn't done great at all but apart from this test where Cook has, no opener has scored any runs at all.
Openers averages - Cook 28, Darwan 23, Rahul 16, Jennings 18
I think that will be taken into account.
