I have heard they are pretty good. The good news is they've got some good size on them, especially their line. They need to toughen up a bit and they'll be ready to roll!
Yes, Burke should have a decent game and he might surprise you by showing up at FB on a few downs.
McDade will hopefully get a few downs, but definately be ready for next week against Soddy.
They both, along with several others have a ton of potential if they keep progressing as they are. Looking forward to Williams, Woods, and Higdon next year as well! Too many young guns to mention...sorry if I left you out, but the outlook is very good!
