Subs per game (MLS coaches)

A few weeks ago, I looked at subs per game in MLS, and more specifically which teams had used the most and fewest subs all time. Now, I've organized the data by coach so we can take a look at how they rank in their usage of substitutes. There are 47 men who have managed at least one MLS game (using the official registry at mlsnet, which includes interim coaches). I only included the 24 who have managed at least 50 games. Average Games 1 Jeffries Mike 2.91 78 2 Andrulis Greg 2.83 124 3 Fitzgerald Tom 2.79 144 4 Clarke Colin 2.75 68 5 Dir Dave 2.70 160 6 Myernick Glen 2.63 128 7 Quinn Brian 2.63 76 8 Zambrano Octavio 2.62 143 9 Nowak Peter 2.58 62 10 Schmid Sigi 2.58 164 11 Clavijo Fernando 2.56 98 12 Sarachan Dave 2.55 92 13 Arena Bruce 2.50 96 14 Bradley Bob 2.47 240 15 Gansler Bob 2.46 204 16 Osiander Lothar 2.38 79 17 Hudson Ray 2.36 108 18 Hankinson Tim 2.36 195 19 Wortman Ivo 2.34 53 20 Rongen Thomas 2.27 190 21 Newman Ron 2.22 100 22 Yallop Frank 2.19 84 23 Nicol Steve 2.17 115 24 Kinnear Dominic 2.03 62 Right now, Sampson (40 games, 2.74) and Ellinger (32, 2.63) would both place in the top ten. It's interesting that the men coaching the two best teams last year (regular season, anyway) rank dead last here. Maybe when you have a good team, you don't want to mess with it. Kinnear and Yallop had some good teams to manage, but Nicol's Revs haven't been good for his entire tenure. It also seems that when the reigns are passed to the assistant, the subs per game doesn't change much. Just look at Fitzgerald (2.79) to Andrulis (2.83) to Warzycha (2.94, not on the list). Or Yallop to Kinnear. Like I mentioned previously, it seems that foreigners are more likely to be at the bottom, while the Americans dominate at the top. That's something worth looking into further. It would be interesting to see which nationalities use more subs.
