Strength Needed

Bench makes your chest and shoulders look better, and maybe your triceps but to say it makes your arms look better is ridiculous. Bench is very much used by anyone coming out of their stance and surely not a worthless lift.

No doubt. I used to have a pretty good bench but it didn't help my arms at all. Triceps a bit.
 
Bench Press isn't a good lift when it comes to what lineman do. You aren't lying on the ground pushing weight up and down. A lot of blocking is in the lower body and hips. you need lifts that work on explosiveness both in legs and upper body.
