There are other thoughts and many of them are probably valid.
But unless I only have 11 players and my opponent only has 11 players I usually prefer to kick with agility teams (and most teams in general). As dragonloup said, its easy to walk right into a 2-1 grind by receiving. If they manage to force you to score early, you're now using an AG team to defend for possibly the next 12 turns. If you have lots of ball hunting skills that may be great, but a lot of times it just means you get ground down.
I would rather my opponent be in that position. When you get the ball first there is a lot of pressure to score and knock out some players. If either of those doesn't go great you can really be at a disadvantage. Though if they do manage to score on turn 8 and knock out several players you may be in trouble as well...
Points for kicking first:
- It's easier to defend with 11 players, something AG teams may not have in the second half
- It forces the other team to attempt to have to not only score, but do it in as many turns as possible while also trying to damage your players. It can be difficult to safely control the ball and mount a damaging offense.
- Even if they do score many AG teams have a decent rate of success at two or one turn touchdowns, and going into the half tied is a nice advantage
- If you are able to stop their drive and score you'll have a large advantage being up a score and getting the ball to start the 2nd half
- Those LOS hits can really hurt many AG teams
- If you lost several players on the first drive it can completely decide the game
- Bash teams have a harder time scoring quick, so even if you score half way through the half it could put them in a position where they need to throw or do other risky things, and you could capitalize on it.
