Skyline LB Wallace in Under Armour spotlight

ESPN Recruiting's Craig Haubert and Billy Tucker took a look at some of the key matchups heading into Wednesday night's Under Armour All-America Game, which can be seen at 6 p.m. on ESPN.

One of the matchups spotlighted involves Dallas Skyline linebacker Anthony Wallace, playing for the White team, and Red team running back Isaiah Crowell of Columbus, Ga.

This matchup has been building during the week. The top back in the country can be elusive, but has also showed deceptive strength and power between the tackles. Crowell, from Carver High School in Columbus, Ga., has the ability to gain yards after contact, but also the ability to bounce plays to the perimeter and accelerate for big yards. It will be interesting to see the battle between Crowell and Wallace, a prototypical, downhill run stuffer. Wallace, from Skyline High School in Dallas, Texas, can be very tough inside and his instincts allow him to quickly get into position pursuing off-tackle, which helps mask a slight lack of ideal athleticism for the position.

These two could meet for some big collisions on runs between the tackles and test Crowell's inline strength. However, the real test will come for Wallace and whether he can match up with the talented back on the perimeter. Both these players have highlighted strengths, but the key to this matchup will be which one can better exploit the other's weakness.
