No surprises here. Head coach Jon Gruden is only entering year 3 of his 10-year megacontract and he hasn't screwed anything up so he's staying. His offensive coordinator Greg Olsen and defensive coordinator Paul Guenther have both been inoffensive so both are being retained as well.
This rookie class is absurdly deep. There were 6 RBs selected in the first two rounds of the NFL draft and 11 in the first three rounds. There were 6 WRs selected in the first round and another 7 selected in the 2nd round. By comparison, the previous 5 years saw an average of 3.8 RBs and 7.8 receivers in the first 2 rounds. The 2020 draft was deeper at both the RB and WR positions than recent years have been, which has pushed some exciting players down dynasty draft boards and made it difficult to make the case that it's an outrage that Player X isn’t going in the top Y picks – but damn it I’m gonna try!
