Inside Zone Question about BSLber

I would think the regular I, because if you offset the fullback weak it usually tells the defense inside zone is coming because the fullback is in that position to block the DE (shorter path than in regular I). Offsetting the FB strong and having him come across to block the DE is good too.

If you really want to keep the BSLB at bay use the fullback to block him on the inside zone. Works best with a 1,5 looks backside.
