If this was home plate and I suggested the line is the best on the swipe, I am universally lampooned.
sweet irony.
Let me line up with the "to the line" folks on this one.
All things being equal, IMO the line is best on the swipe. You do sacrifice position if there ends up a play at 2B.
Moving to a 90 in the infield on a play in/from the infield or left side of the field should never be considered unless you like tasting dirt as you are waking up. Also, 90 on a swipe is simply not the best view. straight down it is the best view. That is why a lot of times we go for help on this. Logic tells us PU sees it best on the line.
Then someone will say "90!!!".
The play is developing and it looks like there will be a bad throw/ swipe situation, you can take a step or 2 back towards the line, you dont come in. Youre not going to make the 90 anyway, all your going to be is out of position on the swipe and possibly in the way.
IMO.
