People do throw out some ridiculous 40 times all willy-nilly. I have a friend who plays some college ball at small schools. He always talks about how he runs a 4.3 and all that. He legitimately had a tryout with the Vikings last year and said he didn't run well. I asked what he timed and he said a 4.5 but blamed it on his coach for dropping him off late and not having time to warm up. Truth is, he just probably legit only runs a 4.5, but you could never tell him that.
I was chilling with him the other day and he was talking about some dude on his flag football team that runs a 4.2
I was like "4.2... Right". Some scrub on your ****ing flag football team in BFE, Florida. I'm sure.
The problem with most people is, they don't really pay attention to the combine like guys on this site do. The extent of their knowledge on 40 times come from their local high school coach and hear-say about local players.
I think Chris Johnson has the fastest official, electronically timed 40 with a 4.24. There's no ****ing way my friend would be a half step behind CJ in a race.
