Sixth and seventh rounds
Alexander has several good qualities. One is that he played at LSU, which, of course, is in the SEC, which is the closest thing the NFL has to a minor league system. Alexander will have been matched up against future NFL receivers. He also has good size at 6'2" and 190 pounds and can tackle in space.
Yurosek is a classic Stanford receiver, and he has NFL size. He is 6'4" and 245 pounds and knows how to block, which could help the Patriots fairly quickly on obvious passing downs. While not overly quick, Yurosek does have decent straight-ahead speed and should run a 40 in the 4.6 range. He also has pretty good hands and very likely will be a better NFL tight end than he was a college tight end.
Young is a huge receiver at 6'5" with good speed and doesn't mind hitting people once he has the ball. The issue is that he has inconsistent hands. But if he gets the proper coaching, he could be one of the biggest sleepers in the 2024 NFL draft. The Miami product should also be an excellent red zone target for Caleb Williams (or whoever the Patriots get as QB1 for 2024).
