The caliber of both players and coaches in the SWAC pre-integration is absolutely staggering. Nearly every great black player of the 1960s or 1970s came from that conference or from another HBCU.
Off the all-time AFL team, Clem Daniels (Prairie View A&M), Winston Hill (Texas Southern), Willie Brown and Buck Buchanan (Grambling), Tombstone Jackson (Southern). From the NFL's all-1960s team came Leroy Kelly (Morgan State), Willie Davis (Grambling), Deacon Jones (South Carolina State), and Lem Barney (Jackson State). From the NFL's all-1970s team were Walter Payton (Jackson State), Art Shell (Maryland-Eastern Shore), Rayfield Wright (Fort Valley State), Larry Little (Bethune-Cookman), Harold Carmichael (Southern), Ken Houston (Prairie View A&M), LC Greenwood (Arkansas-Pine Bluff), and Robert Brazile (Jackson State).
Yeah, these guys could play a little football. That doesn't even include guys like Otis Taylor either.
