The PFF one is very repetitive, at least with the default settings, I find it plays out pretty much the same way over and over again. I don’t believe the draft is that predictable, in fact I know for a fact it isn’t, so it could definitely use some more randomness, but that’s the one I’ve used the most. I usually don’t do trades, it’s hard enough to make it believable without the trades.
I like the NFL mock draft simulator the best since the rankings are consensus, not their own (but yes, the trades are absurd). PFF and PFN are too wildly different on certain guys versus consensus, though at least now you can change the public vs. PFF settings on their simulator.
The biggest problem I have with PFF is their player pool isn’t deep enough. No Jordan McFadden, not Justin Marshall, no Marte Mapu. The late rounds are dull and always the same guy.
It’s funny because last year, Malcolm Rodriguez kept being near the top of the board when I picked in round 6 and it stemmed some conversation about him…and then we actually picked him and he was a stud. Not that I knew that he was going to be, it was just the luck of how their board worked.
