Squad building and management
Form and morale
Form is a player's recent output; morale is the mood behind it. Both shift the odds on the field and both can be managed.
Form is how well a player has performed recently; morale is how the player, and the dressing room, feels about it. The two feed each other and both change the odds on the field.
A batter in form sees the ball early, trusts his footwork and middles the mistimed shot; one out of form plays the same shots a fraction late and nicks them. Bowlers in form land their plans, and bowlers out of form lose their length and their economy with it. Form usually turns on a few innings, which is why a captain will give a struggling player a run of matches, and why one big score can start a streak.
Morale is broader. It rises with wins, selection, a settled role and a fair contract; it falls with a run of defeats, being dropped, being pushed down the batting order, or watching a rival get paid more. Low morale spreads. Managers protect it by being clear about roles, backing players through short slumps, rotating before exhaustion sets in, and picking a captain the room respects.
In Masterstroke: form and morale are both visible and both move the odds on the field, and the commentary says so out loud when a batter in touch middles one or a slump gets exposed.
