Perkins could be a better game QB then practice, however, his struggles currently is not being able to go through progressions of the play, when it breaks down, he takes off. Now Perkins does run well, but I think all of us was hoping that part of his game would improve Also he does not have the strongest arm, his deep ball floats and is usually off target.
Luis Perez offers nothing IMHO, so if Perkins does not showcase improvement in preseason I believe they will cut bait and then make a decision as to adding Perkins to the practice squad or looking for another developmental QB.
