I'll take a stab at the first and second team:
First team
Bamba
Azubuike
Young
Evans
Carter
Second team
Graham
Lecomte
Lard
Wade
Brodziansky
Although I could see Mykhailiuk taking Lard's place because they want another guard and because KU.
IMO, Lard should definitely be there. First in offensive rebounds, 9th in defensive rebounds, 4th in blocked shots, 2nd in field goal percentage, 18th in scoring, 5th in double-doubles.
I don't think Wigginton has the consistency yet. And there are a lot of deserving players in the Big XII this year.
You're not crazy to put Lard on 2nd team. If you look at stats in just Big 12 play he has 1st team level stats...but since ISU is not a great team this year he should probably be 2nd or 3rd team. If he doesn't make 2nd or 3rd team he'll be the best statistical Big 12 player I've seen not do so.
10th in scoring (above Bamba and could very well finish as high as 7th if he keeps playing the way he is)
2nd in rebounding (he was 3 per game behind Bamba just a few weeks ago and now only 1.5)
2nd in FG% (above Bamba)
3rd in blocks
1st in offensive rebounds
4th in defensive rebounds
Only 26th in minutes played...imagine what just more minutes does for him next year.
Best shooting performance in a Big 12 game. 10-11
Most rebounds in a Big 12 game. 17
5th in double double games.
