As for Clark, Rice, Dawson, etc., I think these were good players, but not great.  Sounding like an arrogant a55, I don't buy the logic that: "Well, Chick Hafey is in, so we need to put Cesar Cedeno in, too."  I want to up the quality of the Hall, not water it down more because there were some bad (and really bad) past decisions.  Those three guys should have been HOFers, but, to me, they just didn't finish strongly enough to warrant inclusion.  For the record, my fave players growing up were Cesar Cedeno, Andre Dawson, pre-injury Ellis Valentine, Jim Rice, and JR Richard.  But I wouldn't put any of them in with a good conscience.

The only other guy I might consider is Trammell.  He had many solid seasons with the bat as squatch points out, and many crappy seasons.  Defensively, he more than held his own, and that's verified by the stats today.  And he had that "leadership" that gets sportswriters all weak-kneed and drippy.  Putting Tram in wouldn't make me physically ill.

Goose was the absolutely dominant as a reliever for ten years. From 1975 through 1985 (with 1986 wasted as a starter) Gossage threw 979 innings over 556 games. He allowed an era of only 2.09 and saved 254 games. By comparison, over his best ten year stretch (1996-2005), Rivera has a 2.04 era over 740 innings with 379 saves. Gossage compares pretty favorably to, arguably, the best relief pitcher ever.

Albert Belle was a great player for nine years. If he had a normal three year wind down to pad his career stats, he'd be in without question. (450 hr, 1500 RBI) There are two ways to be a HOFer (in my book) sustained very very goodness over a long period or sustained dominance over a shorter one.  The last couple of years of most guys' careers don't contribute to either.

On the other hand - he does have 438 career homeruns, 1591 RBI's and 314 stolen bases along with over 500 doubles and almost 100 triples.  

Defensively - he had 8 seasons of over 10 assists and 157 career assists.  He also is responsible for 30 DP's and played over 1000 games in both CF and RF.  

I personally believe the years in Montreal and the fact that he probably fell short of marks like 500 HR's due to games played may hurt him but he sure was amazing for the Cubs in 1987 (which he played 153 games in) and was one of the most feared OF's in baseball in his time.  He has 4787 Total Bases in 9927 AB's - pretty darn awesome.

He pitched over 100 innings 5 times and faced over 400 batters in a season 6 times.  

He has a career 2.83 ERA, 300 saves and over 1000 innings pitched and was in the MVP voting multiple times which is why he gets so much love.

For what it is worth - most say he is a sure in as no one has ever had as many votes as he did last year and not made it in the following year.

I am not sure if I think he deserves it but he is one of the top closers you think of any time you talk about the position.  To me - it is Gossage, Sutter, Smith, Eckersley and Rivera.  

There are current day players that could or will be talked about however most of today's closers did not do what Sutter did.

The most innings a closer pitched this year was Mariano and Street at 78.  Last year Gagne pitched 82 innings, Foulke pitched 86 in 2003.  These closers today are required to do less and get more glory.  Come in, make 1 pitch, get a save, pad stats.  The closers from the 70's and 80's faced much different expectations.  The starter went 7, 8 or even 9 which also gave closers fewer chances then in today's game.  

Sutter was highly regarded in his era and just looking at his numbers against the inflated save numbers we see today is not a fair comparison to what he actually accomplished.
