Who's the first place you look for rankings? Tell me and I'll compare their rankings to NFL.com over the last few years and lets see which has the better accuracy rate. I think we'll find they're pretty much the same.
I haven't found your statement about them being incompetent to be true. Or should I say, I haven't found them to be any more incompetent than any other rating organization. What I like about them is that they set a numerical ranking. Whereas CBS, for example, merely ranks them in their perceived order at a position and predicts the round they should be taken.
For example, they list four OTs with Scherff ranked #1 followed by Collins, Peat and Flowers in that order projected to go in the 1st round. At OG they have Cann and Tomlinson rated #1 and #2 and projected to go in the second round. How much do they like Scherff better than they like Collins? Unknown.
Here's what CBS says about Scherff: "
PLAYER COMPARISON: Zack Martin, Cowboys -- Scherff is athletic enough to remain outside at tackle but his build and physicality could be even more effective inside at guard".
So why not rate him compared to other OGs instead of other OTs? NFL.com lumps them all together as OL and compares their relative merits as a group. Using their their own criteria of course.
Here's what NFL.com says about Scherff: "
Like former Hawkeye Riley Reiff, Scherff has measurables and traits to play tackle in the league but might be better suited to play guard."
I see no difference.
In any case though, I'm not taking anything they say as the truth, I'm merely looking at their relative rankings. Both in a particular year and compared to other years. I could have used other sites rankings but I've noticed through the years that they all pretty much have the same top 100 players with only minor deviations.
My own personal feeling on this subject is that you should stick with one organization or one evaluator and follow them every year. It's the only way I've found to rank the relative merits of the players in the draft as a whole and at particular positions when comparing one draft to another draft. It really doesn't matter which organization of individual evaluator you use because we're just talking about trends and relative evaluations here.
If you want accuracy you should just follow the opinions of ours own experts here at the ROD.
