I'm adapting it to BB2016/DZ1&2, of course.Also I hoped for some criticism from true BB veterans hanging around here
Here is what I'm trying to address with this idea, first:
1. Appearance of re-drafting adds additional needs to constantly prepare substitutions for your core positionals so you would have another experienced one when the current star will start to cost you too much due to constant urge to retire. But it may be a bit hard to prepare those substitutions as this means that at some point you may need to, say, fire one of your developed wardancers and hire a rookie one, thus suddenly and irrevocably dropping your team effectiveness until the rookie will see some "level-ups". Will be even harder to achieve for positionals which are usually fielded as a single player, like throwers, or big guys.
2. Under new rules team's cash is now limited severely with EM, making it hard for some squishy teams to gather a good stash of money in advance, to be able to recover from some unlucky disastrous matches they often have.
3. BB is supposed to be a fantasy football team management game, but this aspect still leaves a lot to be desired. Now seeing those neat ideas in DZ1&2, regarding offseason/re-drafting and home/own stadiums, it's clear that GW intends to expand this part of game. My idea adds to this part as well.
4. There are certain positionals in some teams which rarely see fielding, because they are only situationally useful. Like, Assassins in Dark Elves roster, or some Big Guys. They are often not used at all by many coaches as they may only be useful in certain matches, while bloat TV in all of them, unless you fire them right after that (waste of money, SPPs and can't develop them this way). That's just a waste of good game material, and should be somehow addressed.
Now the idea itself:
Each team gets new short support roster for its scrub players (1-3 players long). Players put there stop being counted towards its TV (while still preserving all their SPPs; injuries do work the same way as for players in the main roster there), and cannot be fielded after match is started; they also don't get MVPs. Thus you can now easily have said Assassin which you only need in your matches against elves and stunties, and keep him in scrubs for the rest of your matches (so at least it start being fielded from time to time); or you could have this goblin with DP which most of Orcs teams usually don't use, and keep him in scrubs till some very special match where you may need him finally. Thus all those interesting guys may actually see some fielding, after all, bumping up variety a bit.
Or you could buy certain positionals in advance with spare money, and put them there (thus it addresses mentioned issue with squishy teams, they now can prepare spare players in advance, without bloating their TV). In such case you should be allowed to keep more positionals of certain type than you are usually allowed by your team's roster (of course, you still can't field more than that).
So, for example, you could have 2 active Wardancers in your Wood Elves team, and one extra you bought after some time and put into scrubs. So you can sometimes field him instead of one of those active dancers, allowing him to earn some SPPs - thus preparing a substitution for your main dancers, as they will retire one day (or meet sudden demise). As you can rotate him back into scrubs after that, your team doesn't see sudden drop in effectiveness, you can control it and adjust it according to what opponent you'll face next.
One additional interesting benefit of scrubs roster is that it will allow to put some of your valuable players in there if you think there will be too much risk of them getting injuries in the upcoming match, substituting them with rookies, for example. So adds additional freedom for team management part of the game.
A final note: as now teams, generally, become bigger (due to the fact coaches start to keep 1-3 additional players in scrubs roster constantly), the re-drafting rules may need some tweaking as well, so coaches would get a bit more money, so they would be able to pay that additional upkeep.
Edit:
It's still an open question whether or not players mostly spending their time in scrubs roster should have their number of seasons devised the same way as active players do. After all, they don't see that much carnage as the latter do
I believe the whole retirement thing deals not with their biological age, but more with amount of physical and psychological traumas accumulated in a harsh world of BB Though it would make calculations harder, there could be some threshold for participated matches set, which, unless exceeded, would make them "age", say, 2 times slower.For example, in case of 25% threshold and 20 matches played by the team in this season, if some of the scrubs played in just 5 or less of those matches, then this season is counted as 1/2 of a season in terms of re-drafting mechanics, for them (rounding down). They still need to have their number of seasons increased steadily, as otherwise the feature will be abused by putting some of your developed star players into scrubs to slow down their "seasons played" counter and only take them out on some rare occasions in important matches. To combat it even more, the "1/2 rule" could only be applied to fairly inexperienced players in scrubs, like, until they reach lv4 or lv5.
Edit2:
In addition to said above, to reduce number of calculations and facilitate preparations of substitutions for your key players, unless the said threshold is reached, "seasons played" counter may not be increased at all for scrub players below lv2 or lv3.
