Foster appears to be showing Jerry the door in parallel with how Jarmond showed Chip the door. Demotion.
Let's not be shocked or amazed to see Jerry move on next year. Let's not call him out and blame him for leaving, even if it causes temporary inconvenience for this ship of fools called Ucla football. If it happens, it's been instigated by Ucla.
Foster may sense that Jer is a rival in that Jer is highly popular and visible with the Bruin fan base. Maybe even more so than Foster. Some have called Jerry a HC in waiting, so demote him and get him to walk. Express regrets as his departure but in a Machiavellian manner, rejoice.
