for one he's using florida....tell him to stop being gay and man up and use other teams...(u also..yall using the top 2 teams man...the games more fun when u use underdogs)
2nd..to stop blitz...make ur TE a blocker along with/ or ur RB and Fb pending the sets ur running..my coach always told me...slants kill blitz.....
if he wants to blitz..locate the DB/LB thats coming and slant or send a route in that direction and get the ball out fast..in some cases than none its a 1st down....make sure ur TE/FB/HB is blocking from the direction the blitz is coming....
to blitz..since ur a beginner, id advise u to use the packages in the play books and just send those, sounds like ur not advanced enough to audible ur own blitz with different positions...so mix it up...blitz some LB some times, send a safety every blue moon...
if he wants to run with tebow..send ur corners..and user D with the safeties to cover the wr's to the strong arm side (right since tebows right handed) ur CPU can cover the left side since he has to throw across the body, longer distance, easier coverage for ur safety.
to stop passing...ehh...try this:
1.send pressure to the QB...if he wants to throw...make him throw FAST as possible and not sit back there with 10 sec to pick a WR...
2. use man and zones...switch it up so he can predict the defense ur going to use...
3. zone blitz...use some D where u send men and sit back so when he throws a bad ball ur there to PICK 6!...
lastly, dealing with tebow...id blitz like crazy if it were me...
