Agree. Hairston has an eye for a good pass to make a great play happen. But he is week in other areas including winning battles, holding the ball, and he is also prone to some poor decisions when under pressure. If he can improve his tenacity, think quicker and not get pushed around he'll definitely show some improvement, but he may also end up as an also-ran. Hope he can improve his weak areas b/c his ability to make a dangerous pass is valuable.
Albeit they were only preseason games I would have taken Edward 7 days to Sunday over Galindo. I hope they are not signing him only because of his pedigree because he looked awful. Edward definitely had more consistency in his play over Galindo. Tough to know fully I guess since I don't see them in practice, but, it doesn't surprise me that they would sign Galindo only for his relationship to Arsenal.
