After the exciting 49ers win over the previously undefeated Lions, the coaches had a little scuffle. Jim Harbaugh was over exuberant in his handshake with Jim Schwartz at "mid field". Harbaugh shook with his right hand then (what appeared to be) shoved Schwartz out of the way with his left hand as he moved towards his exiting of the field.
Schwartz is known for being excitable during a victory and it appears he is able to dish it out, and not take it.
I understand the handshake is showing sportsmanship, but is it mandatory? What if the coaches hate each other?
I liked the hostility, but hope it's not something that happens every week.
Off topic comment, as someone else pointed out, why can't the coaches wear suits if they are provided by the league's apparel designer/producer?
