To be honest, a sweep is always hard to predict especially in the case of the Clippers who despite the sweep are a decent and talented team.
Most analysts would stick to the safer "in 5" rather than boldly predict a sweep, especially in the semifinals where it is not so common to have sweeps. Spurs in 5 makes them look alright whether the Spurs win in 4 or in 6, effectively it makes them look like they're not that far off so they feel safer as evidenced by the 8 analysts who predicted Spurs in 5 and only 1 analyst predicted Spurs in 4. Same goes for the Jazz series, where 7 ESPN analysts predicted Spurs in 5 and only 2 ESPN analysts predicted Spurs in 4 (David Thorpe, Michael Wilbon).
