From a make believe, storyline perspective, I could totally accept that the "system" is putting players in a position to succeed. You hear about it all the time - players enter a new system, and thrive when they didn't really thrive before. Or a team lets a player go and replaces him with someone else because it's the system that gets the production. It's how I tried to justify why, for 2 years straight, I had the top QB in terms of passing yardage, one of the top WR's in terms of receiving yards (in year 1, Crabtree was #1, in year 2, he was #3), and one of the top RB's in terms of rushing yards (I don't remember where Gore was ranked year 1, but year 2 he was #2, while Crabtree was the NFL's #3 receiver, and Vince Young was #1 in passing yardage while winning the NFL MVP award - year 1 had Alex Smith lead the league in passing yards, along with 38 INT's, Frank Gore had 1100+ rushing yards, and I had 2 1000 yard receivers in Michael Crabtree - 1800+ yards, and Vernon Davis - 1400+ yards)
But I do believe its a lot of "cheesing". I put Michael Crabtree in the slot in every offensive formation, not cheesing, but because that's how I wanted to utilize Crabtree's skill set. But it did turn into "cheesing", because running a receiver on a slant route from the slot receiver position is next to unstoppable. Running Crabtree in the slot position from I-Twins formation and running him on slant patterns is how I racked up 1800+ yards.
As far as Frank Gore goes, I'd run a lot of slam, blast, and power plays. Typically, I'd try to run to the left side behind my 2 best linemen, Staley and Iupati, or I'd run powers to the right behind Snyder and Davis with Iupati pulling.
One of my "money plays" was from a single back formation that had 4 WR's on the field. One receiver to the left, 3 to the right. I'd flip it so the run would go to the left. With it being a 4 WR set, it'd spread out the defense, and I guess since the receivers weren't balanced, it'd cause the CPU to call bad defenses. It basically went like this:
-If the defense was in a 4 man front, I'd run the play, because there would be a double team block on one of the defensive linemen, springing Gore free.
-If the defense went pass defense heavy with a 3 man line, I'd watch the linebackers. If the linebacker stayed over the line, I'd audible to a quick pass. The inside receiver would be free, hot route him on a slant, and bam, easy completion for easy yards. If the linebacker went out to cover the receiver, then my 5 man line would dominate the 3 man defensive line, springing Gore free for big gains.
The Power O wasn't a "money play", but due to the formation and how the CPU AI reacts to it, it was worth running the play because the play was typically either a really short gain (no gain, 1 or 2 yards) or a huge gain (50, 75 yard TD runs).
HB Blast plays from I Formation, Strong I, or Weak I, were regularly 10-15 yard gainers. If not, it'd still typically get me a good 4-7 yard gain.
The big thing though, is that at least in last year's game, I noticed that a higher rated running back would actually get better protection from his blockers. I actually originally noticed this in the return game - Reggie Smith, an 80 something speed rated safety, was one of my highest rated kick returners. I could never understand why. But I noticed his was getting better returns than a lot of 95+ speed returners who had low KR ratings, and I noticed it was because the blocking was ALWAYS better for Smith than it was for the speed guys with low KR ratings (not talking about guys like Ginn). I noticed the same thing about running backs. If Frank Gore was hurt, or needed a sub to spell him, I never got the same results because all of a sudden, the blocking simply wasn't there.
It seems that one of the running-with-the-ball ratings impacts the types of blocks the runner gets. I didn't get to run with Kendall Hunter enough to really test that in this year's game (Frank Gore was hardly ever injured, and hardly ever needed to be spelled). So maybe that's the factor - Frank Gore gets those wide open holes because he's got the ratings that give him good blocking.
