TE Juwan Johnson undergoing surgery for foot injury and expected to miss camp time

JJ is not a special tight end, he is serviceable at best. Hopefully Kubiak and DA can find an upgrade. I often hear the NFL is a copy cat league, but for some reason the Saints ignore the fact that most successful teams have a legit tight end. How long has it been since the Saints invested in the position? Who was the last really good tight end to wear the black and gold?
Here are the leading tight ends each year for the team with yardage after Jimmy left the first time:
15-B Watson 825
16-C Fleener 631
17-C Fleener 295
18-B Watson 400
19-J Cook 705
20-J Cook 504
21-A Trautman 263
22-J Johnson 508
23-J Johnson 368

There definitely seemed to be a shift in philosophy once Kamara was drafted, although Jared Cook did well in 2019. Johnson was building a good rapport with Andy Dalton in 22, but took a step back last year. I'm sure Kubiak would've loved to have seen Bowers drafted, but hopefully he can get the most out of someone
