ExtraTime Radio: All things refereeing with PRO GM Peter Walton & Chris Penso

We wouldn't dream of leaving you hanging during the holidays, so the boys at ETR set about creating four shows to get everyone through the end of 2014.

Dec. 22: Referees (PRO's GM Peter Walton and Chris Penso)

Dec. 25: Americans Abroad (Alejandro Bedoya, Herediano owner David Patey, Kabul Premier League vet Nicholas Pugliese)

Dec. 29: Expansion (Atlanta MLS president Darren Earles, LAFC president and co-owner Tom Penn)

Jan. 1: ETR Book Club (The Numbers Game with author David Sally)

In this episode, PRO GM Peter Walton reviews the year in MLS refereeing in 2014 and what is to come in 2015. He says more than 90 percent of the calls were correct this year, and explains how they aim to improve the process even more.

Referee Chris Penso then joins the guys to talk about what he gave up to pick up the whistle full time, and what it was like refereeing the inaugural Hero Indian Super League match.
