This, my friend, we are in complete agreement. BU did not have the length or athleticism to run his defense last year. Questions remain about the incoming players ability to play defense and questions remain over the effectiveness of BU's scheme in the B1G.
The bolded regarding BU not having the length or athleticism to run his defense is true. We lacked the personnel and I think most would agree we've brought in recruits that pass the length/athleticism eye test. As far as it being effective in the BIG, I'm not sure that's fair. We had a 22.7% opponent turnovers per possession(4th in the country), which is the highest of any BIG team in the past 8 seasons. We were also 5th in the country in turnovers forced. The 2 point field goal percentage allowed was real bad, no doubt. But we had an impossibly thin front-court and that will surely improve. All in all, considering we did NOT have a long or athletic team and a super thin front-court, those stats are impressive IMO. Year 1 is all about establishing an identity on defense, and we most definitely have accomplished that. It will take some time before it all gets polished.
