We lose 12 scholarship seniors. Looks like Rutgers loses 9. That's not a significant difference.
Well, just going by pure numbers, that's 33% more. So thats absolutely significant. Moreover, you are a smart enough football fan to know that who you lose is rarely as important as who you are replacing them with. If Temple has quality depth, losing 12 starters can be overcome, although a small step back should be expected. If there is not much depth, a larger step back should be expected. Simple as that.
