OK, I'll play. Here are overall shooting and three point shooting percentages of SEC teams that have played the Lady Vols:
Vandy: .454 .326
Texas A&M: .435 .296
Auburn: .412 .282
LSU: .410 .328
Missouri: .393 .320
Arkansas: .382 .299
Georgia: .382 .284
Impressive list of juggernaut offenses isn't it? What's amazing is Tennessee is having one of the worst shooting seasons in program history, but they still rank in the top 4 of the SEC....
Well, you didn't really play because the relevant question is how does the SEC stack-up in the broader context of WCBB? The implication of your post is that the SEC is unusually bad in terms of its offensive proficiency. Well, how about in comparison to the ACC?:
1. Notre Dame 22 684 1366 .501
2. Louisville 21 627 1342 .467
3. Florida State 21 618 1365 .453
4. Duke 21 559 1250 .447
5. Wake Forest 22 547 1255 .436
6. Virginia 21 543 1254 .433
7. Georgia Tech 21 585 1364 .429
8. North Carolina 21 582 1414 .412
9. Pitt 20 523 1277 .410
10. Boston College 20 485 1206 .402
11. Miami 20 494 1240 .398
12. NC State 21 485 1227 .395
13. Virginia Tech 21 454 1178 .385
14. Clemson 21 452 1176 .384
15. Syracuse 21 520 1390 .374
As we know, ND is one of the best offenses in the country (#4 in the country in fact). Louisville has a slightly higher shooting % than Vandy. So, except for ND, the SEC is very much on par.
How about the Big 10? It's a similar story:
1. Maryland 20 631 1295 .487
2. Iowa 20 572 1244 .460
3. Northwestern 20 553 1238 .447
4. Rutgers 20 567 1276 .444
5. Michigan 20 552 1247 .443
6. Ohio State 21 618 1413 .437
7. Minnesota 21 591 1359 .435
8. Indiana 20 545 1265 .431
9. Nebraska 20 515 1222 .421
10. Wisconsin 20 470 1133 .415
11. Michigan State 21 517 1248 .414
12. Illinois 21 535 1320 .405
13. Penn State 21 507 1279 .396
14. Purdue 21 492 1254 .392
And Surprise, surprise, the Big Ten MEN aren't much better!!:
1. Ohio State 22 655 1293 .507
2. Wisconsin 20 518 1062 .488
3. Indiana 21 591 1235 .479
4. Michigan State 21 574 1209 .475
5. Minnesota 22 612 1310 .467
6. Purdue 21 541 1169 .463
7. Penn State 21 511 1165 .439
8. Maryland 22 505 1153 .438
9. Northwestern 20 467 1070 .436
10. Illinois 21 535 1248 .429
11. Nebraska 20 435 1016 .428
12. Iowa 20 466 1121 .416
13. Michigan 21 470 1133 .415
14. Rutgers 22 464 1177 .394
So, it is relative comparisons that matter. The reality is that you have seem to have skewed view of offensive proficiency. Across the board, shooting percentages, are not as high as you imply the norm to be. The statistical fact that the LVs are the #10 scoring defense in the country (and #3 in the SEC) suggests that they are a very good defensive team and a cut above most other programs. And the fact that three SEC teams are in the national top 10 could also imply that the conference has a number of strong defensive teams.
