Scouts and various player personnel officials from every NFL team are expected to attend the Texas A&M Pro Day presented by Opportune. After being measured for their official heights and weights, the Aggies will be tested in the vertical jump, 40-yard dash, 5-10-5 short shuttle, long shuttle, broad jump, 225-pound bench press and the L-drill. The Aggies will be wearing special Pro Day apparel designed by adidas.
According to his agent, Manziel will not throw at Pro Day and will have a separate on-campus workout March 27. Since Manziel is listed in the press release, he will probably appear tomorrow to be measured and participate in non-throwing drills.
Evans, Manziel, and Matthews also participated in the 2014 NFL Combine and you can read Ranger222's analysis of their performances here.
