Ejectionable or not?

[Only a fan]

High School football scenario and result...what would you do?

Team A had what appeared to be 3-4 plays go against them during the first half of the game (inadvertent whistle, interception ruled simultaneous possession, and fouls.) Team B scores on last play of the half.

Middle of third quarter, Team A called for illegal formation on a play where they gained 15+ yards. Very next play Team A comes out in same exact formation and again called for illegal formation. This time they lost 7-10 yards on play...

Now the Coach of Team A comes out beyond the numbers to yell at the officiating crew about the formation being legal. Referee tried to explain to Coach of Team A why it was illegal. Coach wanted no part of it. Referee turns to begin play and Coach of Team A (still out above the numbers and inside the 25 yard line) yells "You guys need to stop screwing my kids!" Coach was assessed a 15 yard penalty and ejected.

Question...would you have ejected the coach for flagrant unsportsmanlike or just assessed the unsportsmanlike penalty?
