There may be some legitimate coaching technique concerns, but a lot has to do with individual efforts, abilities, and talent.
If wasn't too long ago where BD suggested they had to simplify the schemes. That sort of raises a red flag for me.
I'll try an analogy for which many of you may call me nuts
Take some basic math courses in high school as an example. Assume everyone enters high school fairly good at arithmetic. If someone aspires to a profession that requires science and math background, they may run a curriculum through high school that progresses from freshman math to geometry, trigonometry, calculus, advanced calculus, etc.
I and many of may classmates luckily had the ability to excel at the highest level of mathematics. Also, other classmates could do ok at the beginning math class, but eventually digressed from a math/science emphasis because they couldn't master the challenges of more advanced mathematics classes. They never said the teachers stunk,,,,,,,but realized they, on a personal level, wasn't up to the challenge. Never heard the parents of those students that couldn't progress in those lines of study suggest the teachers didn't know what they were doing. Mathematics, absent basics, were beyond comprehension for their kids. Those student went and excelled in other areas of study according to individual abilities and talent.
Now, drawing a parallel with the team.........we have a number of athletes that excelled at the high school level, but may not have the abilities to compete of the BCS level.
Maybe they'd be o.k. in Div. 1-aa, II, or III,.......where the challenges are less intense. Just like the HS students that good in basic math, that is their limit.
I want to make my rambling clear....... I'm not picking on any HS student, or the current players on the team. They are all good people, and try their darnest, but maybe they are also in over their head. Again, BD stated the coaches decided they had to make things simpler.
Don't forget, historically UConn class have not been highly regarded. They have never been considered an offensive powerhouse.
