The top 5 main radio men also appeared on Match of the Day and Murray, ABB and McNamara all missed time covering other sports. Conor didn't commentate at all for 5 Live during the Rugby World Cup though he did plenty of reporting during that tournament.
26 commentaries used the traditional 2 lead commentator format.

So as usual not a clear number 1 summariser, with Claridge doing the most matches but doesn't go to the Euros.
Unusually there were 4 matches where they used 2 summarisers. Guests who contribute once or twice a half were not counted in this list.
