This is different than the high-low concept which is used to beat zone coverage where the routes have a big difference in the depth of the routes.
Play #1 (thumbnail post #56 of this thread)
49ers: 12 personnel - Mesh concept out of a bunch formation
TB: Zone coverage
In theory, this concept will not work against zone coverage and we will see it not gain much here. This is the first pass play of the game. The thumbnail will detail the routes being ran.
Below: The coverage by TB. Cover2, zone under.
Below: Celek is the player setting the mesh (pick). VD will be the beneficiary. But this is zone coverage and no TB defender will be getting picked off.
The play in full: Notice as VD catches the ball, he is smacked by the zone LB as the LB is able to attack downhill to apply a sure tackle for a somewhat minimal gain. Not a horrible play result, but not a big play by any means.
Take a look at the thumbnail post #56 to get a sense for how often HaRo went to this concept. It doesn't have to always be criss crossing over the middle of the field. Plays 12, 14, 27 also use the mesh concept, but on one side of the formation.
Cekek looks like he would have been a better target on that play, I know its kind of contrary but the defense more or less ignored him. Once he passes up the initial defender at about the 42 yard line, the defender goes towards VD and sniffs it out, a quick throw to him would have been much more productive using VD as the decoy.
AR1 @ 13:19 Crabtree @ X (wide left) position, VD off the LOS in the Y (right slot, usually) and Boldin @ the Z (wide right) position. Celek seams up field on the left side of our LT. All 3 run go-routes clearing out VD underneath from right to left behind the DL; hit instantly by CK for 5 yards. Gore flared out late to the right sideline as a outlet.
Not complicated...a common route we run.
