In this case, the freshman was rattled on every play, even after completing some passes, while the junior never was, even though I went deep with him more and he had a lower completion percentage. It was easier for me to see the routes, so I stuck with the junior, who did not throw a pick until the sixth game of the season.
Thanks for the tip on the L2 hot/cold thing. I never knew that. I wonder if that actually translates to a receiver making tougher catches, a running back breaking tackles, etc. (which, BTW, I get very few broken tackles in a season. Not sure if it's the game or my sad stick skillz - probably the latter).
