Here's my take.
The vitriol for Tutu is two fold.
1. He had terribly non existent rookie year, and
2. We could have had or as some claim, should have had Creed Humphrey.
The truth is the way the NFL is changing, the value of all world OL is over stated. What teams had "the best OLs" in the NFL?
If you go by rankings (PFF or OLINERANKINGS), Tampa or Dallas depending on which rankings. They both have them 1-2 but reversed. One had SF #3, the other #9. The other had N.England #3 the other #9. Both had KC and Philly reversed. Ironically both had the Rams #7. One had Cleveland #6, the other #8.
One point is, of the top 10 ranked O lines, 3 missed the postseason and 3 others were 1 and done. That leaves 4 and only 1 of them made the SB.
Another point is, if both had the Rams #7, where would they have been with Humphrey? And would they have won the SB more easily? I and many others contend, if OBJ doesn't go down and Higbee plays, the Rams win in a blowout. Still without Humphrey.
Of the top 10 passing offenses in the NFL, 9 made the postseason and two made the SB. Only 5 OLs were ranked in the top 10 and one was LAC, who didn't make the postseason.
It's not about OL. It's about the QB and the weapons he has at his disposal.
