Given being a PRO Sportsman is such a lucrative and privileged career I do believe you do have to act accordingly because like it or not, you have more influence than you probably should. It looks like his first county realised this and fired him (rightly) but again, another county thinks 'wooo, we get a free bee player'.. They should have looked at his background and most certainly the ECB should have before even being considered for ANY form of ECB training groups or 2020/ODI or Test squads.
Sadly, I don't believe that the 'He was 18' is a valid argument because people know right from wrong. There are 'mistakes' and then there are 'mistakes' that you sadly, can't just erase and given the current world we live in.. you can't just ignore.
Sport is a privileged career and so needs to be treated as such given the money involved in sport. I would prefer to not see him darken any England door again and for his county to look at dropping him but I suspect he will do some 'learning' and be back and as most things in sport.. all forgiven after a few wickets or runs.
After all... One player was 'sacked' just for looking out of the window...... Another gets into fights.. another gets into fight, potentially some drugs etc.... ECB really do show no leadership or consistency. Poor show all round really
