Correct.
History tells us that if you sign too many players after you get promoted it disrupts what t you promoted in the first place. A team can be greater than the sum of it's parts, you shouldn't be changing more than 5 players at once other wise you're asking for trouble. The skill is finding the right ones at the right price.
Which goes against a few of our fans who are OBSESSED with the idea of "total clear out in summer" "get rid of all the dead wood" EVERY. SINGLE. SEASON.
