The issues raised here are spot on.One of the biggest problems in the game are the subjective calls such as holding and pass interference. The 50 yard PI call on a bad throw that is very short rewards and rewards GREATLY poor play. It is way too much of a penalty.Holding is another one that we see non calls at the point of attack and then we see a slight hold on the other side of the play that could have no impact and it nullifies a 30 yard run for a TD.I think these inequities are deciding games a lot more than people think, especially with more parity (I know NE is blowing it out of the water, but there are still 20 teams that interchangeable). Have you ever seen such poor officiating? In the past 4+ years I have been more upset with officiating then ever. Rooting for teams is much harder (which makes fantasy more of an option) because the refs making game changing calls are impacting the outcome. The problem is caused by instant replay in my eyes.First, instant replay by itself is causing the game to change a lot. We have about 2 less possessions a game now because of all the time instant replay was taking; now out of bounds plays only stop the clock momentarily. Now after penalties the clock starts again (even after delay of game which is amazingly stupid). Less possessions gives the lesser team a greater chance to win. (and isn't the purpose of instant replay to allow the better team to win based on how they play?) I would rather a few more possessions decide the outcome.2), I think the instant replay has caused the officiating to get worse as they are unsure to make a call that could be overturned. This is my opinion and I do not have any supporting evidence other than what i see.3) The camera feeds/angles impact whether plays can be seen and reviewed and whether or not they are shown in a expeditious fashion allowing teams the time to review plays is unfair. How many times do we see a team rush to the line to ensure the other team doesn't have time to review the play? It is really bush league, but a smart play. Or how many times just because the play happened at a commercial break and it gave a team a long chance to review do you see them after coming back challenge a play? The whole thing is very unprofessional4) It is absolutely absurd that a coach can't call for an instant replay in the final 2 minutes of the half. Whoever thought of this rule should immediately be fired and never be allowed to give input again? I can understand giving the booth the ability to review a play in that time frame (although I don't like it), but to not allow a coach who has reviews left to do so is absolutely absurd. Having to sit there and hope the booth stops the other team to review a clear mistake is the most illogical part of the entire process.5) And as for this thread, if you are going to allow 2 reviews, why not be able to review the game changing plays such as a 50 yard PI call or a crappy holding call? The opposing answer to this has a point in that we know holding is happening on every call and it is very possible that a holding call is finally made because the guy was warned not to push it and finally a "cumulative" call was made. What I mean is that a guy was on the borderline for holding 3 times, but none was quite a enough but maybe it was, so a 4th time was a cumulative call for holding. These are humans and that is a reasonable way to call it to be fair. It is too easy to say it either is a hold or not as there are a lot of grey areas.6) Finally, IR slows the game down way too much and breaks momentum (especially on booth reviews in the last 2 minutes). This kills the flow of the game and takes away the instant excitement when a play happens (you are always unsure whether you can celebrate or not.That being said, I would eliminate IR all together as the product ion the field is worsened because of it and when you go out of bounds STOP THE CLOCK again! This would be the best for the game. Now before you beat me up for this, you should know that I was a STRONG advocate of IR and said you had to have it. I have since changed my view and think it is killing the game.I know it probably won't go back, but I think the game is worse because of IR. Therefore, if it is here to stay then they should allow any two (or more) plays to be reviewed, but if you are questioning the refs and are wrong it is a 15 yard unsportsmanlike penalty.I am also for 15 yard PI calls as well as spot fouls depending on the severity of the infraction. There is no way you can convince me that some of the calls we see are worthy of a penalty that is more than two times as bad as a 15 yard face mask. I am also for defensive holding being 10 yard and a replay of downs. Giving a 1st down on 3rd and 30 after a chuck 6 yards down field is absurd.So what I am saying is that I would get rid of IR, but knowing that won't happen eliminate the 2 minute review upstairs and allow the coaches on the field to challenge as many plays as they like but if they are wrong they get charged with a 15 yard penalty. i would then allow a 15 yard PI to be called in "less bad" PI situations and also make defensive holding 10 yard and not an auto first down....oh and while I shouldn't be adding anything in my conclusion, can we stop with the refs having to explain their decision to the coaches. just keep play moving.
