Dak has certainly not had a lack of talent around him on offense either. So trying to float that boat is silly. In fact, we've seen that he's only really been able to perform at a high level when everything else around him is working. When things fell apart, such as 2017, he regressed quite a bit.
Further, Rivers only played with Tomlinson for 4 years out of the 13 he was the starter in San Diego. He's put up numbers long after Tomlinson bolted for the Jets and then retirement.
First, remember that the OP didn't talk about the surrounding talent, he was only trying dispel the idea that winning percentage matters by saying Rivers and Tebow also had high winning percentages. So that was the context I was responding in, and therefor it was appropriate to point out those guys still had notably lower winning percentages than Dak.
And remember that I said from the beginning that I agree winning % isn't the only thing to look at with a QB, but in the effort to dispel that, that the argument the OP used actually worked against him.
And, again, there is no way to make a perfectly apples to apples comparison, and I'm not claiming Dak has suffered from a lack of talent, I'm only saying that if a person is going to argue that other QBs have also had a good winning %, that person also has to be willing to accept that Dak's winning % is notably better and that those QBs had talent around them too.
Fair point about Tomlinson - I thought Rivers had him longer than that. But Rivers really didn't suffer from a lack of talent after Tomlinson either. He had a strong RB combo of Tolbert, Mathews and Sproles, and now has Melvin Gordon, and he has had receivers like Keenan Allen, Vincent Jackson and Antonio Gates, who may be the best TE to ever play outside of Tony Gonzales.
