The one downside to this article was that Mr. LaPolice opted to trim his tables down to highlight only a subset of teams in each table.
Using the Drive Search feature on CFLStats.ca, I will fill in the rest for those who are interested. Please note that because I do not have direct access to the stats that TSN uses, my numbers are slightly different. I can't explain these discrepancies, as I'm confident in the accuracy of my data. It's possible that in some cases, our criteria for certain cases is different, for example the total number of possessions (TSN cites 1497 possessions, while my data includes 1485.) Whatever the reason for these discrepancies, they constitute a very small portion of the data and do not change the overall trends of the results.
For each of these datasets, if you click the link to the underlying search, you'll be able to view the stats from the defensive perspective (which team allows the highest TD percentage, etc), as well as each individual drive that matched the results.
There is a slight semantic difference in the search here - "inside the 20" on the drive finder includes the 20 yard line, while the TSN data does not. The actual search results presented here from CFLStats.ca is "Drives inside own 19". That said, the TSN article may mixing the two data sets, as they claim a 21% TD rate for the Stamps, which is correct if I include the 20 yard line, but a 0% rate for the Riders, which is only correct if I omit the 20 yard line. The issue here may be that TSN's source tracks the starting line of scrimmage independently from the CFL's scoring, which is what CFLStats.ca's stats are based off of.
Drives starting from own 21-49
I don't have a good search for this one, I had to search for drives within own 49 and remove the data from drives within own 20. Even still, my numbers are quite different from TSN's here.
I'd very much like to see TSN's source data on this one to compare, because they or I have a big error (or Mr. LaPolice made a mistake in this section). There are minor discrepancies here such as the article crediting the Riders with 9 touchdowns on 21 possessions, vs my data showing 8 touchdowns on 21 possessions, but the big one here is Toronto, which isn't included in the article's data. The article claims that the Riders lead the league with a 43% TD rate, but according to my data, Toronto is way ahead of the pack at 53%.
