Recently hired HCs are bringing in their guys

There seems to be a large push back of the interest between Jimmy G and the Texans. Out of curiosity, I looked up past successful HC hires and looked up how many influential guys they brought in.

When Brian Daboll was hired by the Giants, they took Jon Feliciano (C), Davis webb (QB), Isaiah Hodgins (WR), Antonio Williams (RB), Jack Anderson (G) all from the Bills

When Mike McDaniel was hired by the Dolphins, they took Trent Sherfield (WR), Raheem Mostert (RB), and River Cracraft (WR)

When Sean McDermott was hired by the Bills in 2017, he brought 9 players, in 2018 he signed 5 more in FA, and then a total of 7 more in 2019&2020.
