I don't think there was much that "went down", and probably not any different than LaPo would have done with any of the other teams. In cases of desperate need, teams will poach PR guys, but generally they understand that what comes around goes around, and they do the right thing and handle things man-to-man.
Not saying that if Kenny said no they wouldn't take him - I have no idea. But my guess is Kenny (like most teams) wouldn't deny a player an opportunity unless they had serious future plans for a guy.
Asfor my comment, football's a great game, and an awful business. But, if you like it better, after signing McHenry, McKoy was "allowed to more fully pursue his non-football opportunities".
