If Phillips stays another year (he should for his own good); then with him and Pope it makes 2. Then we have 2 incoming: Williams and Taylor. We could add a third if offered (T2). That would make five on the rooster next year (could have had six, but we know Lingard would have been useless). That's getting very close to where you need to be.
If you want to put an even more positive spin and stretch the definition, you could include players that were 5 stars at one point then were dropped to 4 stars (I'm predicting Garcia is added with one of the final two ICs). If we have a great year in 2021, then maybe add 2-3 more five stars and we will be extremely competitive. The future is bright.
