Rivera Done?

At age 42 with a torn ACL, we may have seen the last of Mariano Rivera.  Where to place Rivera in the pantheon of pitchers?  Rivera has pitched about 1,219 innings, the equivalent of less than 6 seasons as a starter.  He has over 600 "saves" in the modern era.  He won 5 (I think) championships.  His career 9-inning stats are excellent: 7 hits, 2 walks, 8 K's, 2.21 ERA.  The ERA is the best ever in the post-war era for pitchers with over 1,000 innings.  However, I believe that modern relievers are over-valued.  Rivera contributed to less than 5% of his team's innings; compared to a C.C. Sabathia who contributes in around 17%.  Although his managers had great peace of mind knowing that he would close out a close game, in many of his appearances he appeared after the work was done and very seldom had to work in high-stress situations (compared to starters).  I do not know the totals, but a high % of his saves were 3 outs, with no baserunners inherited, and a comfortable lead to work with.  Rivera was no doubt effective, in fact among the 3-out closers of this era, he was probably the best or among the top 2 or 3.  But I cannot go along with those saying today that he is among the great pitchers of all time.  I simply don't think that modern relievers make the impact that many believe they do over a long haul.  And, this is not just a Yankee-hate thing; I say the same thing about Trevor Hoffman.  A guy who pitches a mere 1,200 innings in those circumstances just doesn't cut it as a true all-time great in my book when compared to the whole population of pitchers across history.
