When you have no 1 T20 batsman, no 2 ranked ODI batsman, a bowler who was no 1 in ODIs couple of months ago and struggled with injury but still is no 3,4, a bowler who is ranked no 2 in T20s. Couple of batsman who are fastest and second fastest to thousand runs and othe one who is second fastest to 2000 runs, then definitely you can conclude class is not the issue.
