![]() ![]() In this sequence, the object independent trackers do not give many errors. This could be avoided by including some interaction between the players with an MRF. In this case, dynamical information is not enough to split the two trackers. The failure of AGSMF reported in table 2 is caused by a player who is completely occluded for some frames and has a nearby team mate, who ’attracts’ the tracker of the occluded player. Figures 7 and 8 show also a failure that is avoided by AGSMF, in this case for an occlusion of two ’Liverpool’ players. This failure is avoided if we run AGSMF algorithm as shown in figure 6. Figure 5 shows a failure with IKF when a ’Liverpool’ player jumps and is occluded by a ’Fullham’ player. After a failure was observed, we manually set the player at the right position and resume the algorithm. Table 2 shows the results in terms of tracking failures. Therefore the pixels that have the same colour model for X t and for X t + δX t does not contribute to the difference. In any case, we have to compare the likelihood for a state X t and for a nearby state X t + δX t. In addition, what we need is not exactly log φ ( Z t | X t ), but its gradient, see equation 18, which is computed numerically as a difference. In equation 23 we intend to obtain weights by comparing nearby positions in a grid. For practical purposes, the sum in equations 22 or 23 does not have to extend over all the image pixels. Thank you for taking the time to join me as we study the new Oregon offensive system here at. Please let me know what you think of this “picture book” format below in the comments section. This article is a different type of analysis and format than the previous X’s vs. The best defenses are the ones that make the least amount of mental errors, and understand the how and why behind all the window dressing offenses use to create hesitation and confusion. It requires intense preparation to play sound defense. ![]() As a result, the game can, and often is, decided before the kickoff. Football is an instinctual game once you start “thinking” instead of reacting, you’re at a disadvantage as a football player. Motion from the offense usually requires and/or elicits a response from the defense.Īnytime the offense can hear the gears turning in the heads of the defenders, it has gained an edge. Not only is this a quads formation, but the jet motion adds yet another element the defense must respect. Nevertheless, this play highlights how Taggart’s offense employs unique formations that test defenders’ discipline and communication skills in a high pressure environment. Some defensive coordinators will even specifically gameplan blitzes like this to be mixed in with their base checks, just to keep the offense on its toes and hopefully force a negative play. The defense is practically guaranteed a free rusher against this empty pass protection scheme. The aggressive Cat Blitz (above) is especially well-suited to disrupt a play that needs time to develop. I’m not suggesting that Oregon would not have had success on this play against these alternative defensive schemes, but WSU could have been in a better position to defend this well-designed, well-executed scheme from the Ducks, had they checked to one of the above man coverage options. Due to the fact that the routes require time to develop, and to create more space for the crossing route, the concept is typically attached to a play action fake (as it is in our example). This classic two-on-one scenario demands proper technique from this defender as well as disciplined play from the underneath defenders as the route concept develops.Īnd while this is the play’s primary design, it is a versatile concept that can be effective against other types of zone and man coverages. By sending S3 on an intermediate crossing pattern and sending another receiving threat up the seam, the defender is placed in a bind. This concept stresses the defender responsible for the vertical of the #3 receiver (S3). ![]() This concept has spread like wildfire through the college ranks in recent years as split field coverage checks in response to trips (3 WRs to one side) and quads (4 WRs to one side) formations have become the norm. In the above diagram, you can see the route combination Oregon employed. ![]()
