It's painfully obvious that this team cannot guard any decent opponent in man to man. Painfully obvious to even the most casual fan of basketball.
By this point of the season, the staff/Cal should have recognized this fact and taught them to play zone. We have good enough athletes to play reasonably well in zone, I believe. Today's, the Zags who are above average at best, had how many shots within 4' of the basket? Possession after possession, they got a great look right at the rim.
And we played man defense every single time. No excuse for that. None.
