I'm not suggesting we get rid of Arroyo for some magic beans, quite the contrary. I just think we need to act while teams are interested because Arroyo's dim shine is, in my opinion, beginning to fade.
And, yes, he does have potential. He could be another Mussina if he starts to locate his fastball, but Mussina never had those control problems. If he's only topping out around 90mph, he needs to be able to work the strikezone in and out, up and down to be effective. He keeps getting behind batters with missed fastballs and they are just camping out at 2-0 looking for meatball curve in the zone.
Barring injuries, the Yankees rotation has 4 pitchers who were the #1 (Johnson, Mussina, Pavano, Brown) on the teams they left to come to NY, and a #2 (Wright). While we don't quite lay out the dough like they do, at the amount of money we spend, we shouldn't have anything worse than a #3 in the rotation. Arroyo is #4 or #5 and won't be better than that without location.
