The problem is you can't force Zeke on a DB 10 plays in a row. Again, it's a false assumption that there will be no LBs to be found and that opposing defenses wouldn't play a 4 WR set that runs the ball 50% of the time differently than we have traditionally seen them play 4 WR sets that run the ball 25% of the time. If I believed the LBs would somehow be out of the picture and Zeke would be left alone to consistently break through the LOS for a big game with only a DB to try and stop him, I would be all on board, but that's a simplistic and unrealistic view of how it would work.
Consider this (and I admit it's not a perfect analogy) ..... if a team were to run a surprise onside kick 10 times over a season, they might be successful 4 out of the 10 times. But if they were to run it 50 times, does that mean they would be effective 20 times? The answer is absolutely not because opponents would learn the team's tendencies and plan for it. The same applies to this. A 4 WR set can open up some nice running lanes at times when the opposing defense is defending against a team that passes 75% of the time, but if the team ran the ball 50% of the time the rate of success would go down because opponents would learn the team's tendencies and plan for it.
it does not work quite like that.
1. you put 4 wr - each of which are wr2/2r3 types. of those 4 receivers, a couple of them will get the 3rd and 4th cbs of the defense. furthermore, all the wrs are decent route runners unlike a couple wrs that are no longer with the team. some of you are talking like these wrs are like wr4, but thompson was the top receiver in buffalo last season and is a decent route runner. hurns is at least a wr2. beas demands more than single defender...
2. the defense can go 5 dbs and 6 dbs. you cannot force them to go 6dbs, but you have 2 wrs that run 4.3, and 2 of the wr are likely to have an advantage of their cb3 and cb4. if the wrs win enough, then the defense will be forced to have less lb and more dbs.
3. the goal is to force the defense to have less in the box and have more dbs. one way you do that is to put more speed in the wrs - we have done that. the other way is to line up more players wide, 4wrs does that.
4. so the most the defense can have is 7 in the box, and that is really risky if a couple wrs have advantages over their cbs. furthermore, you can attack the 7 in a box by having motion like jet sweep. if they are in a zone, you will get an extra blocker with a jet sweep if the rb goes in the same direction as the jet sweep.
5. so dak can simply read the defense with the motion. if he sees it is zone and if zeke is designed to go in the opposite direction, he could take the ball himself (pass or scramble) and follow the jet sweep because he will have a man advantage. if it is zone and zeke is designed to follow the jet sweep in the same direction, then he would give zeke or the wr the ball. if it is man and zeke is designed to go in the opposite direction, then he could give zeke the ball and he would only have the cb to beat. on and on...
6. it is not as if no one in the nfl runs rpo from the 10 personnel. i already shown examples with the eagles.
