Again, tackling is mostly a player problem, not a coaching problem. Yes, coaches are responsible for making sure that tackling is good and that tackling improves and is consistent, but in the end, it's the players who play the game and do the tackling.
Some players are better tacklers than others. It's just a fact. Some teams are better tackling teams than others. Everyone agrees that UM should be better and more consistent at tackling. I didn't think tackling, yesterday, was as weak as it had been in some other games.
It is much more difficult to tackle at the college level than in high school. In college, the players with the ball are faster and bigger, and the offenses are more complicated and are executed better. High school players with good speed can be good at making tackles, without having great tackling technique, because they are faster than most other players.
It's hard to tackle in space generally, and it's hard to make tackles when the defender doesn't have the best angle or is a split second late getting to the ideal point of contact. Coaches need to help players get into better position, and to react quicker to the play. Some of this depends on the defense called, but most of it doesn't. If the defender is not quite to the ideal spot to make the tackle, it will be harder to make a good tackle, or even bring down the runner.
Tackling also depends at times, on what teammates are doing to help, and how close to the play they are. If teammates aren't closing in, there's more space for the runner to cut or juke.
Not wrapping up more often and things like that are more discipline matters. Coaches need to ride players for not doing certain basic tackling techniques like that.
A player can't and shouldn't be judged by one or two noticeable tacklers per game. A player has to be evaluated on all tackles. Everybody misses tackles, gets juked, or makes mistakes. The best tacklers have few of these tackling issues; the poorer tacklers have more of them.
While UM still works on tackling from time to time during the season, it's harder to work on tackling because only a practice or two per week has full contact. There's just not enough opportunity to tackle at full speed, or to tackle in scrimmage situations, during the season.
Several teams UM has played this year were very good tacklers. Most haven't been any better than UM, or worse.
