"You have to help protect them because it's not a small problem. If you are honest it's the same as alcoholism or getting addicted to drugs.

The Austrian coach's strict regime has yet to pay dividends. Southampton is sitting 16th in the Premier League, just two points clear of relegation.
Cellphone breaks for social media fix
Hasenhuttl's comments come on the heels of a move by a US NFL coach to give his players "cellphone breaks" so they could satisfy their need for a constant social media fix.
Kliff Kingsbury, the Arizona Cardinals' first-year coach, said he's going to give players the social media time-outs during team meetings in the week leading up to game day.
"They're itching to get to those things," he said (via ESPN) Tuesday during the NFL owners' meetings in Arizona.
Kingsbury hopes to cut down on distractions with the breaks, which he gave players when he was coaching at Texas Tech. The breaks he'll give his pro players, whose average age is 25, will come every 20-30 minutes.
"You start to see kind of hands twitching and legs shaking, and you know they need to get that social media fix," he said, "so we'll let them hop over there and then get back in the meeting and refocus."
