Some staggering attacking numbers and trends from this year's Brentford that together paint a very coherent picture, and also have strong implications for a hypothetical future where Frank is given the time and the resources to optimize this.
- 20th in total number of passes inside the opponents' final third. Teams that have mastered the art of possession play usually lead the way in this; Liverpool, City, Woolwich and Chelsea in that order constitute the top 4.
- 19th in pass success rate inside the opponents' final third. The same as above: City, Liverpool, Chelsea and Woolwich are 1st, 2nd, 3rd and 5th respectively
- 3rd in percentage of passes that are forward, as opposed to sideways or backwards. This correlates inversely, although imperfectly, with how much emphasis a team puts on possession play: City, Chelsea, Woolwich and Liverpool are 20th, 19th, 18th and 15th respectively.
- 14th in number of through balls. Teams that emphasize possession play lead the way in this as well: City, Woolwich, United, Chelsea and Liverpool in that order constitute the top 5. The correlation is once again imperfect though, as one of the most direct teams in the league in Palace are 7th for example.
- 15th in number of sequences that involve at least 10 passes: Another variable that correlates positively with possession play. City, Liverpool, Woolwich and Chelsea in that order constitute the top 4.
- 2nd in direct speed, defined as the distance the ball gets progressed by a team divided by sequence time. The inverse correlation between this and possession play is weaker but still discernible: City, Chelsea and Woolwich are 20th, 19th and 14th respectively.
- 18th in average number of passes made per sequence. Another variable that rather strongly correlates with possession play: City, Liverpool, Chelsea and Woolwich in that order constitute the top 4.
- 18th in average sequence time: Same as above.
- 20th in number of build-ups, defined as the number of sequences from open play where a team completes at least 10 passes before either launching a shot or getting a touch inside the opponent's box. Again, a strong correlation with possession play: City, Liverpool, Woolwich and Chelsea lead the league.
- 1st in number of fast breaks, defined as sequences where a team quickly turns defense to attack after winning the ball inside their own half. The name implies an obvious inverse correlation with possession play, but the evidence is rather mixed: Chelsea, Liverpool, City, Palace, West Ham and Woolwich in that order are the following 6 teams.

Unless Keith Andrews in a matter of 6 months has completely reversed what he inherited from Frank, an explanation that would violate Occam's Razor quite badly, what we see right now is also what we would get from Frank even years down the road.
An optimized version of this could finish inside top 5 in a rather open season one day, after all he had two top 10 finishes in his 4 seasons already; but I don't think the whole endeavour would be worth it from a return on investment standpoint.
Success is not solely a matter of gradual improvement; opportunity costs of all the time and money that a manager receives during his tenure also come into the equation. I can see Frank passing the former test, by finishing let's say 12th, 9th and 7th respectively in three seasons including this one, while still failing the latter.
