I don't have all the numbers for the Jays under John Gibbons but I did crunch the numbers for the 2005, 2006 and 2007 seasons - the only three where Gibbons was manager all season. The Jays did not have much of a running team in any of those three seasons - Vernon Wells and Alex Rios were their speed guys.
2005 - 72 for 107 - 67%
2006 - 65 for 98 - 66%
2007 - 57 for 79 - 72%
As you can see, the Jays got less aggressive on the base paths each season under Gibbons, although I think that's more about personnel than anything. What's important is they never really got any more successful at running. I don't know if ~70% is a good success rate or not but hopefully that helps.
