Tyrann Mathieu compared to Jourdan Lewis

[CalPolyTechnique]

This might be difficult to understand if you have not put in the work of posting the measurable(s) of hundreds of players over the years. Nevertheless, I'll try to explain.

Not all players participate at the combine.

If I post the times from 2 players that both participated at the combine and 1 or both also participated in a Pro Day, then when someone inevitably asks for the times of a 3rd player, the times become muddled.

Player 1: Combine and Pro Day (Pro Day was better).
Player 2: Combine only.
Player 3: Pro Day Only.

If I originally posted the combine times for players 1 and 2, then when someone inevitable asks to compare player 3, the situation is this:
Player 1: Combine times posted.
Player 2: Combine times posted.
Player 3: Pro Day times posted.

Now although player 1 had better times at his Pro Day, only his combine times are being compared to player 3's Pro Day times.

Players that participate at the combine have the option to participate at a Pro Day.

The combine only player had the option to participate at a Pro Day so it's not as if that player is disadvantaged by compared him to another players Pro Day numbers.

If I just use the best times, then none of this is an issue.

You're not comparing three players. You're comparing two (Matheiu vs. Lewis).

Both participated at the Combine.

The second you stray away from comparing like-to-like (i.e. Combine) the information gets muddied. Even when comparing just Pro Day times you lose the level playing ground because of all the variables (field type, conditions, which hand-timing is reported, et cetera) and are notoriously unreliable.

As an example:
Player 1 participates at the Combine so you use his times.
Player 2 also participated at the Combine, but you also use cherry-picked times from his Pro Day held on a fast outdoor track with a tail-wind that day.
Player 3 only has his college Pro Day numbers that was held four weeks after the Combine on a grass field.

Combine times/measures aren't the end-all-be-all, but it's the closest thing to establishing a level playing ground when comparing prospects.

I put Mathieu first intentionally. I didn't want any chance of the thread getting merged with another Lewis thread. It was painful for me to read the thread title as it is definitely backwards.

Fair enough. There's method to your madness.

If you want to post information, then go for it.

Look at the complete thread. People have requested the measurable(s) for multiple other players.

I've posted the measurable(s) for hundreds of players over the years while you've likely done Jack Squat.
