No great secret that it's a bit of a different analytics era now where the midrange is largely shunned in the NBA, and that's spilled into college. We have bought into that philosophy quite a bit in recent years - we only took one 2-point shot yesterday that wasn't in the paint. Lamb developed that trademark floater, but the analytics people now describe the floater as the worst shot in basketball, so the NBA would probably coach that right back out of him if he played today.
Not saying we should have been a contender in 2012 - but it was a rather catastrophic dropoff after losing only one player, however great that player may have been (when we had his replacement waiting as an understudy, who proved to be quite competent). If we don't beat West Virginia in overtime in the BET quarters, we might not have made it in. Lamb realistically isn't near the top of the list of reasons to blame for that - he improved from his first year to his second and took on more responsibility. But when we asked him to make the leap from Robin to Batman, which was probably good for his personal development, it was part of a broken puzzle. We saw some of the same things happen with Scott Burrell, Albert Mouring and Jerome Dyson, too. All of whom also had future first-team All-Americans and/or lottery picks in their supporting casts. Boat to some degree could be included (although that year, I think DD leaving and Purvis not really being all that Ferrarish left our talent level too thin, whereas those other seasons, we got way better the next year - going from NIT to the Top 10).
The roster didn't really fit in 2011, either. We didn't have anyone to play the 4 - our stretch fours weren't strong enough or good enough shooters (Roscoe, JCD), Olander started token minutes. We would play Okwandu and Oriakhi together. That was a mess. Oriakhi was not a good post option for a 4-out, 1-in style of play. The 2023 team didn't necessarily fit either on paper - Newton and Jackson got in each other's way on offense (neither spaced the floor well when the other had it), and Sanogo and Clingan were two of our five best players and couldn't play together.
