This. Against a guy like Persa, blitzing is not the answer, IMO. 1. He can effectively read the blitz, and 2. He is just a snake, very elusive, which helps negate the effect of the blitz. I've wanted to see us play more press coverage against Northwestern's receivers. Their entire passing attack is built around those 5-12 yard passes. Make them EARN those yards, don't just give it to them.
Michigan State has the talent to beat us. But as you said, they aren't disciplined enough. And neither are the vast majority of teams that we play. They just aren't that patient, and their offenses are more predicated on stretching the field vertically anyway. Which is why the way we do things is so effective. It's just that we haven't seemed to make the adjustments to our Achilles' heel.
Press coverage with who?
Prater? Prater is/was still a bit undersized and loses plenty of battles against bigger, more physical WRs. He's on record stating that he wants to get bigger and stronger for his SR campaign ... and that is part of the reason why he didn't jump to the NFL after his JR campaign. [the '10 season marked his 3rd year on campus]
Hyde? Hyde is a little bigger, but he's still young and lanky ... and furthermore he was still a bit inexperienced. [the '10 season marked his 2nd year on campus]
Bernstine? Bernstine is big, physical, and fast enough ... however, he's repeatedly been noted as still being a bit on the inconsistent side in coverage. [4th year on campus ... but injured a lot in prior years]
Castillo? From what I understand, Castillo is still a bit on the slow side. As a result, if a WR gets a step on him in press-coverage ... then he's beat. [3rd year on campus]
Furthermore, when executing press-coverage, you still need the LBs to be effective in their coverage responsibilities too. If you watched the Northwestern game, then you quickly realized that Persa was keeping an eye on whomever was covered by LBs (particularly, those who were covered by Troy Johnson). Even if Iowa employed press-coverage, we'd still likely be stuck with a LB in coverage (to cover Dunsmore or the RB) ... and Persa still would have eaten us alive there. And, on top of that, without the safety help over the top, Persa likely would have been able to burn us more for big-gainers too.
Now look to the PAST.
In '07:
Godfrey - Big, fast, strong, .... AND EXPERIENCED! After being mediocre, at best, in '06 ... Godfrey really put things together as a SR. He had the strength to win many battles when jamming guys ... AND, on top of that, he had the speed to get back if the WR got a step on him. [4th year on campus ... a TR SR]
Fletcher - Big, strong, and pretty fast ... AND pretty experienced! After really sucking in '05 and '06, Fletcher really started showing flashes in '06. He was mainly brought in when we needed a physical DB to execute press-coverage. He got beat a bit by Hardy ... however, we got killed more there because we were missing our starting MIKE LB and FS (Shada was playing FS in that game). To Fletcher's credit, Hardy only had something like 4 grabs on the day ... but missed tackles on him is a big part of what killed us. [4th year on campus ... a RS JR]
In '08:
Fletcher - Big, strong, pretty fast, and EXPERIENCED! Otherwise see above .... he's a guy who already had a good bit of experience in press-coverage too. [5th year on campus ... a RS SR]
Spievey - Good size, very good speed and great athleticism, ... and surprisingly confident for his first year back from ICCC. Also, it's worth noting that he had a full year of starts under his belt in the JUCO ranks ... where he was really successful and played really aggressively. A lot of folks threw the ball in his direction ... however, he really responded well and developed pretty quickly. [3rd year in college ... a RS SO]
THE POINT: Just look at the personnel in '07 and '08 ... both seasons where we executed a good bit of press-coverage. In those seasons we had guys who could pull it off. We had guys who were either athletically a bit freakish OR we had guys who turned out to be phenomenal cover-guys.
In '09, Spievey and Prater were a great duo, however, part of our success there was that we were able to give safety-help on Prater's side. Don't get me wrong, Prater was very good ... we were notably better in coverage with him in than when we had Lowe or Castillo in instead. However, Prater was still a little short ... and he would sometimes make bad reads.
In '10, I really liked both Prater and Hyde ... however, Prater simply wasn't as good as Spievey. Thus, we couldn't really give Hyde extra safety help without it leaving Prater on an island. And, as we all witnessed, Prater got burned for big plays many times when he was stuck on islands. Thus, we really weren't well suited to pull off press-coverage.
