I felt like the tackling today was subpar, at least for a couple players. In particular I saw Sash miss at least a few tackles trying to hit guys down rather than use good form. I think ISU had some tough ball carriers and WR's that didn't go down easily, but it doesn't matter - you still need to hit, rap and drive, not just hit.
And those that posted above are 100% correct - form tackling is unquestionably becoming a lost art, and in particular becoming a dangerous endeavor b/c so many players drop and lead w/ their heads.
