I think this is certainly true about Springer, as he is a guy who really needs his athleticism. With Keuchel, I'd say it depends how he does this year and then responds next. If he has a '15 level workload this year, and his arm responds well next year (and not like '16 in any semblance--performance or soreness/injury), I think they'd consider an extension and that he might age well given that he isn't a hard thrower. But more than likely, I agree that they won't overpay. I feel like many of us might be assuming that he won't respond well next year if he throws a large workload this year. Let's see. It's certainly a risk I'm factoring in now.
Hard throwers have more velocity to spare than Keuchel and can pick up old man tricks like throwing the ball down and out of the zone a lot. Keuchel already has mastered this and if he throws it any lower the ball is going to bounce like a grounder into the strike zone.
Are you being sarcastic in a way that I don't get? The OP said something correct. The first reply tried to tell him he was wrong--but he wasn't. End.
This makes no sense at all. Why should they be high in payroll now if they know they have big bills coming up after that?
