Coaches do not care a bit about whether the CR speeds up the game. They care about not having their catchers and pitchers exert or injure themselves on the base paths.
Sometimes the CR's bring more speed, but since these players aren't in the starting lineup, they often lack the base running savvy to take advantage of that speed. Stats for Gnats may be able to tell us whether, as a group, CR's are more likely to get picked off than players in the line-up.
As a practical matter, the plate umpire determines speed of game, regardless of whether courtesy runners are used. If he keeps batters in the box, gets new balls in play promptly, hustles, doesn't let mound conferences drag on, and keeps both teams aware that he cares about the time limits for warm ups, for batters to get into the box and for pitchers to deliver the ball, the game will proceed at an appropriate pace.
I agree on your observation about a coach’s perspective in general.
We don’t have the CR here for the regular season, so the only times I see it are during the summer and fall, or if we play someplace where it is in effect. I will say though, that as an SK it causes me problems, and I don’t like it.
You make a great point about substitutes pinch running. I can’t say for sure because I don’t track whether a runner was a substitute for the player who reached base, but I sure can express my opinion based on observation.
Subs sure SEEM to have more trouble on the bases, not just for pickoffs, but in all phases of base running. My perception is they miss more signs, get poorer “reads” from pitchers, have more difficulty establishing leadoffs, have more difficulty reading a BIP as to whether it will get through or drop in, picking up the 3rd base coach while running, and I‘m sure a myriad of other problems. And you used a great word to describe it. SAVVY. A lot of it has to do with getting opportunities, but it is definitely an issue.
I grabbed some data to see if I could at least give some support to the idea that fewer opportunities on the bases tends to cause problems. See attachment.
I pulled all the players on teams I’ve scored for since 2002 who had either gotten picked or had a stolen base attempt. I realize it’s easier for me to see what’s going on because I know these kids, but I’d think it was fairly telling that the players with the fewest PAs sure seem to get picked and caught stealing with more regularity than those who got to hit more regularly.
