Beware the assistant coach.He can be as seductive as ice cream, or as bitter as vinegar.He can startle you with quick success, or break your heart with constant defeat.He can sprout like a giant before your eyes, or shrink in stature and skulk off in the sunset.But one thing you always can say about an assistant coach - when elevated to the position of head coach: Nobody knows nothing.So don't tell me Jim Schwartz is a great bet for success to lead the Lions, or I will tell you the same was said of Rod Marinelli, who just finished an 0-16 year.
