You're the first person I know to claim they thought the 09-10 team was NCAA level before the year started. Lazar was the only proven commodity. Acker and Cooby both looked like disappointments, DJO and Buycks were complete unknowns, and neither Fulce nor Butler had shown much to suggest they'd be more than bit players.
Anyway...the truth is this team simply hasn't met potential. Jamil hasn't grown into a stud like we've seen happen in the past with Blue, Crowder, DJO, and Butler. Gardner has had moments, but for the most part the new rules have hurt more than helped him. Mayo hasn't taken the step that we saw Blue take as a junior. And both McKay and Blue left before the season started. The ultimate irony is that the two guys most people expected relatively little out of statistically, Derrick and Jake, are the two that are taking the brunt of the criticism despite the simple truth that the guys most expected to deliver on the statistical end aren't doing so and yet aren't getting the same criticism.
Is this team underachieving? Yes, because the expectation was that guys like Jamil, Gardner, and Mayo would take the same kind of steps forward we've seen from guys like Jimmy, Jae, and Blue in recent years. Instead, they have simply stagnated or in many regards even regressed. But what the hell...let's point the finger at Derrick and Jake.
