My thoughts:
Lance Lynn is probably gone. Weight is going to be his biggest issue, but it's not like guys like David Wells haven't had success either. He has the stuff to be a starter in a Big League rotation.
I think Satterwhite is gone as well. He is probably going to be a reliever in the pros, so I wouldn't worry about his numbers this year as a starter.
Scott Bittle should be gone as well. More than likely, he will be a relief pitcher is the pros, but he could start if he learns how to throw another pitch for strikes.
Aaron Weatherford also probably will leave. I may be biased, but I like him better than Bittle, but there may be more risk with Weatherford because of his history or arm injuries. I wouldn't worry too much about that because his velocity is still there and I love his composure and makeup on the mound. His confidence is his best asset.
I'm interested to see what happens with Brandon Turner. He could be a steal for someone late in the draft. He can flat out hit, and he has some pop. He's not very versatile- he's a second baseman or nothing- and of course, there's the hamstring issues.
I also think Ole Miss will lose Cody Overbeck and Logan Power as well. Overbeck can hit for power and average, and his defense seems to have improved when I have seen Ole Miss play. Power has some, well power, and can hit as well. His best asset is his arm, though.
If I was a team, I would take a flyer on Justin Pigott, throw him in the bullpen or teach him how to throw a knuckleball. He's a competitior if nothing else.
I'm also interested to see what happens to Jesse Carver since I have heard that some teams like him. He will be a project, but you never know.
