My mistake on the 18 minute stretch.
I still thunk Manu us more susceptible to injury coming in colf=d off the bench.
To me most critical times of a game are:
1. Begiining of a game. Ideally get off to a strong start but at a minimum not fall way behind and be climbing up hill, messing up your rotations the rest of the half.
2. End of the first half, last 4-5 minutes. Finish strong.
3. Beginning of the third. Again maintain a lead, stay even or climb back in.
4. Fourth quarter of a tight game.
That's when Manu needs to be in.
