Possible consequences under WA criminal code for robbery

My friend is in jail for robbery. He has a long criminal history for misd. driving offenses and a couple of felonies. His public defender states that the prosecutor is offering robbery 2 with 72 months and a strike. The lawyer states that if not taken the prosecutor will change to a robbery 1, but this crime does not meet those guidelines (no weapon/not at a financial institution); He does not feel that his lawyer has his best interest in mind. Any suggestions on what he should do? He is not sure if he should take the deal or continue to trial (afraid he will get the max robbery 1 sentence). They are not forthcoming with evidence against him in this case and the lawyer is trying to rush him into the deal;
