Houston Dynamo losing strikers

The defending champions Houston Dynamo are losing strikers left and right.  Paul Daglish was released at the end of last year.  Nate Jaqua is supposedly looking for a job in Austria and it was just announced that Joseph Ngwenya is on his way to Austria.

Ngwenya has just signed a deal with SK Austria and keeps him there until the end of the current Austrian season with an option to add another full season.  SK Austria is currently at the bottom of the top Austrian league approximately half way through their season.

Assuming Jaqua goes as well, this leaves the Dynamo with Brian Ching as the only real proven striker on the roster.  As of right now Corey Ashe, Dwayne De Rosario, Brian Mullan, and Erik Ustruck are the only players on the roster listed as forwards or M-F.  De Rosario and Mullan are more suited to play in the middle.  I don’t know much about Ashe or Ustruck.  Dynamo fans – you want to depend on Ashe or Ustruck to partner with Ching this year, or do you move De Rosario and Mullan share time moving forward to partner with Ching?
