Agreed. I think Miami is the only team that runs a version of that offense without physical WRs who can block and they got bullied late in the year and in the playoffs. I've mentioned it on here and I know someone else has a well, if we want to protect Olave and Shaheed, we will have to bring in a couple physical receivers. One of those could be a TE like Bowers and then an X like Legette. ATP is big, but I still see a finesse WR in him right now, maybe a Big Z and not necessarily a X. That's perfectly fine if we address the X with someone like Legette or another physical X from the draft. 2 TE sets with Bowers and JJ would be difficult to deal with with AK in the backfield and Legette/Olave, Legette/Shaheed or Legette/ATP at WR. Hell, that would be 4 receiving threats 6'4" or bigger if it was Bowers, JJ, Legette and ATP.
Someone to watch in FA as an old school X WR is Donovan Peoples Jones.
