Rather than having the managerial basestealing setting be vague (e.g. 'infrequent' vs. 'aggressive'), could we also install basestealing thresholds based on ratings?  

For example...  
Minimum baserunning rating to attempt to steal 2nd, 70 and up
Minimum speed rating to attempt to steal 2nd, 60 and up
Minimum baserunning rating to attempt to steal 3rd, 80 and up
Minimum speed rating to attempt to steal 3rd, 80 and up

Seems like a relatively straightforward programming change.  Also, this would mean that I might never again look at a box score and say, 'What the...!  Why on *earth* did the computer instruct *that* guy to swipe a bag??'  Unless of course that guy meets the specified thresholds I plugged in, in which case I know exactly why... and exactly how to stop it next time.  

And like many other things, this could be a big deal when the manager gets ejected, since the bench coach could ignore the settings and start sending in the steal sign to baserunning turds.
