Furthermore,about Bob Sanders, he is a guy who: has Averaged less than 7 games per season over his 8 year career, a guy who has finished as many season on the IR as he has off the IR, has never once played a full season, has only had 2 good years in the NFL out of 8 which happened to be the only 2 years he played more than 6 games. and lastly, a guy who was picked in the 2nd round. Do you think mentioning his name helps or hurts your your argument that Mathieu will be considered a 1st round talent at safety? Personally, I kinda feel like you just proved my point for me and I think most NFL teams would admit that Bob Sanders was too small to be a safety in the NFL and his durability suffered for it.
I just do not see him being selected by a team to play safety prior to him being selected by a team to play corner. He is a FAR better prospect at corner. Teams need 3 good corners now since for most teams the nickle defense is on the field more than 60% of the time. The only way I see him being considered a safety 1st is if he runs a horrible 40 at the combine. Even then, he still wouldn't be considered a 1st round safety talent.
