Sounds constitutional; however, didn’t the courts rule in the case of Maurice Clarett (sp) (super freshman running back at Ohio State a few years back) that the NFL is a business and can set its’ own rules of employment ??
While I do not remember the particulars, I believe he lost and in fact never played in the NFL.
Whether this falls under age discrimination or not, I will let the legal guys on the board chime in.
IHMO, extremely few guys are ready both physically or mentally for life in the NBA or NFL.
Whether they should be given a chance or not is not my problem. However, I do think that the teams have the right to say no.
