just that will not get you bigger, comming from a hs football player. heres what we do 2 days a week

Bench-5x5
squat-5x5
-then we mix it up, we will do two of the following, bent over rows-over head press-cleans-sumo DL-reg DL

then the other 2 days we do a circut for 30 minutes which is h*ll lol
4 step over hurdles (hip flexers)
1 350lb tire flip
30 yard block walk and shrug-cinder blocks
40 yard sled push-a little metal sled with a rod to put weight on and we use 45's
5 cleans
6 dips
5 over head squat
5(each leg) split squat-you take a rubber weight and put your back foot on it and do a lunge basically

but as z said you need to run as well, lifting isnt jsut the whole thing
