No not all his bad. The timing problem was partially the function of a bad pass into him. If it had been firmer, quicker he would have not had to move up and had more time. He also can't play it off the one touch because none of his other players are in proper position. His only options were to smack it up or kick it out. We don't know what instruction the coach has given in the event his players are not open....some will come down on the keeper if they don't try to maintain possession since they want possession before anything so the kids can learn.
Doesn't the striker partially cause the trip by reaching into to try and get the ball?
He could have easily hit that ball wide left, to the back that sent him the slow ball, and cleared any danger. "if" this and "if" that... defenders don't always hit perfect balls... especially on a shitty surface. And please don't say he couldn't have hit a 90-degree ball to his left and avoided the striker... because that's exactly the right play. Oops... too late... you already did.
P.S. - There is bias with keepers for sure... they 99% of the time get the benefit of the doubt. All a keeper has to do, and I was one for many years, is go down and raise a hand for the foul.
