INDIANAPOLIS -- If you needed any validation that former Auburn tackle Greg Robinson is a top NFL prospect, he showed why once again Saturday morning when he ran an official 4.92 and an unofficial 40 time of 4.84 with a 1.68 10-yard split. Robinson weighs 332 lbs. 

Those times left NFL Draft observers drooling.

Robinson's first attempt was a 4.88. Which already was ridiculously fast for a man of Robinson's size.

There will be debate moving forward from this event whether Robinson or Texas A&M's Jake Matthews should be the first tackle taken in the draft.

Two of our four CBSSports.com mock drafters have the Rams drafting a tackle with the No. 2 overall pick (Rob Rang thinks it'll be Robinson, while Pete Prisco says it'll be Matthews). Which would be interesting since Robinson is much more raw than Matthews.
