I'll ignore your unnecessary insults and give you a more detailed explanation.
Having one player score 60 points in 82 games, means he's playing and contributing the whole season. Points aren't the only thing that matters in hockey.
He could be a hitting machine, he could be great on the PP and/or PK, he could be amazing at cycling the puck and applying sustained pressure in the o-zone, he could be a faceoff wizard (if he's a C), he could be great defensively, he could be a forechecking/backchecking machine, a breakaway machine, etc, etc. Unless he's a pure offensive player and a complete defensive liability, he will be greatly contributing every time he's on the ice, regardless if he's scoring points, and his play will contribute to the team winning games.
In your scenario, you have an extremely talented guy that's always injured, so every time he's missing games you have to shuffle a top 9 tweener/ third line guy/ 4th line grinder in your top 6 or top line, depending on where this 2 ppg player is playing. Then you'd be relying on an AHL-er to replace that tweener on your 3rd/4th line. Suddenly, instead of relying on an amazingly consistent forward, you have to juggle 3 different players, and constaly shuffle your lines, so line/team chemistry becomes an issue. Without even going into cap hit complications since I doubt you'd be paying the injury prone 2ppg player pennies on the dollar; you'd constantly have to be calling-up and relying on random responsible AHL-ers and pray they actually contribute something and able to hold their own; and your issues will be further exposed in the playoffs, where teams either roll 4 deep lines, or they double-shift their top lines. So, now the question becomes, how comfortable are you with the plug in your top 6 and the AHL-er in your 4th line?
