He is what he is, not what you, I, or the next guy wants him to be. Keita has carried a team that has deficiencies and holes everywhere to an amazing and unpredictable season. No need to start picking his game apart now.
So he isn't the demonstrative and "take over a game" guy you want him to be. Just sit back and enjoy the ride and just remember that any game they play in, win or lose, from this point on, is a game none of us thought they would even be playing. This team is not playing very well and teams are exploiting their weaknesses (PSU x's 3)...... so just enjoy it for what it is.
