he also pulled an oblique and will miss at least one start.

Colon will be inconsistent, that is the nature of the injury. His FB was always straight as an arrow and we lit him up like a Christmas tree. His biggest calling card was how well he threw his curveball off of his FB. If he truly is throwing mid to high 90s again, then the questions that you need to know are..
A. Is he locating well enough to be effective
B. Is he locating his curve

If both A and B are yes, then he is a steal. If not, he might have the velocity, but he wont be very useful.
