Franchise cricket restricts how many overseas players may take the field in any match. That single limit governs recruitment, selection and the price paid for domestic talent.
The limit applies to the eleven, not the squad
Teams may sign more overseas players than they can field, so the constraint bites at selection rather than at the auction table. Squad depth and match-day strength are separate problems with separate budgets.
A squad might carry several international stars while only a handful can play together, which means expensive players spend matches watching.
Recruiting overseas depth is therefore insurance against injury and unavailability rather than a way of strengthening the first-choice side.
Domestic players carry a scarcity premium
Because most places in the eleven must go to home players, the market for capable domestic cricketers is far tighter than the market for imports.
An uncapped domestic all-rounder who fills a difficult role can attract bidding that looks disproportionate against his international record.
The premium is a direct consequence of the rule, since teams are competing for a restricted pool to fill the majority of their positions. The pool is finite and every team needs the same profiles from it.
Availability windows complicate the calculation
International players are frequently unavailable for part of a season because of national commitments, so a signing may only cover a portion of the fixtures.
Teams weigh a player's likely availability alongside his ability, and a consistently available performer can be worth more than a superior but absent one.
Late replacements are permitted for this reason, though a replacement signed mid-tournament has little time to adapt to conditions. A short run of matches rarely justifies a specialist signing.
Selection becomes a puzzle of roles
With limited overseas slots, teams cannot simply pick their four best foreign players. They must cover the roles domestic players cannot fill.
A team well supplied with domestic spinners will spend its overseas places on fast bowling or middle-order power, and the reverse holds elsewhere.
This is why apparently similar squads produce very different selections, and why a change of venue can prompt a wholesale reshuffle. The eleven is assembled from constraints as much as from preferences.
The rule protects the domestic game
Without a limit, teams would field the strongest available eleven regardless of nationality, and home players would lose the exposure the league was created to provide.
Restricting overseas places guarantees that emerging domestic cricketers share dressing rooms and match situations with established internationals.
That development function is the stated justification for a rule that otherwise reduces the quality of the cricket on display.
