I think we are stuck with Schonert for this year. Edwards needs help. Jim Kelly is perfect. I always thought he was a little too agressive with his throws (I know what you think but it's my opinion and I am entitled to it!). Edwards is timid to a fault. Perhaps day in and day out exposure to Jim Kelly for a month or so could whip Trent into a more aggressive attitude.
Granted Edwards will never be a gunslinger (I don't want one), but maybe he could become more than he appears to be.
