Aahhh- I see it's the you found the problem so you have to fix it mentality- fair enough and since you asked-
1) Be aware of the play clock. I see other teams pump their hands towards the sky and get the play clock reset when applicable. I have never seen Flacco or any other O' player make this motion. If not able to reset the clock, at the very least be aware that you either have 40 or 25 seconds to run a play. Flacco, in his 9th year, should be highly cognizant by now that he does not have limitless time to stand around and then run a play at his desired time.
From a coaching stand point- be aware that a play clock is running and if you're $120M QB is ignorantly standing around, radio in, send a player, burn a flare, do something to wake him up and get moving. For the QB and coaching staff to miss the play clock all together and have to take a time out <2 minutes into any game or quarter is ridiculous.
2) Excessive clock waste while losing is just unpalatable from a fan standpoint. The game in New England was not over, yet the Ravens entire staff allowed 6 minutes to burn off the clock. Why? Not like they were struggling for a play. Time and time again, players were jogging to the line or the line was set and Flacco would take his time getting into formation. Makes no sense. Run the no huddle or the sugar huddle. At the very least burn less than half the play clock between plays. This starts with the coaching staff and needs to run through the players. A sense of urgency when losing. Simply controlling the clock and realizing that a large amount of the 4th qtr has burned off and you have not moved the ball should put a fire under their collective butt. Not to mention, we had already wasted time outs early in the 2nd half because of point 1.
Either way- be aware that this is a clock management game. Whether its game or play clock, be aware of it.
