Pierre Vercheval was interviewed by CFLman and this is what he had to say about Mike Walker (Translated)
Since I am a linesman, I would choose DT Mike Walker of the Tiger Cats. I had to play him during my first 4 seasons. He was an animal ! He mastered all the techniques, he had it all. Strenght, Power, Read plays, super intimidating, grinning with that gold tooth shining through that black visor. By far the best defensive linesman I ever played.Might bring memories to some.
Walker's name belongs on anything that talks about great CFL D linemen. One of the greatest ever. The only former Ti-Cat I would put before him is Mosca.
Great Story
Personally...I didn't need Pierre Vercheval to tell me how GREAT Mike Walker was.
Mike and Grover were a great combo. Unseen since Mosca and Barrow.
Mike Walker was terrific. Not to take anything away from him, but John Barrow was much better than Mosca or Walker. He was probably the best DT in CFL history. 16 All-Star selections in 14 seasons sums up his career. I’d take either Walker or Mosca alongside him.
How does that math work? Do you mean combining league all-star and division all-star selections? I'm not sure if you have to be a division all-star to be selected league all-star. But that's the only way I could figure that would work. Maybe you meant 14 all-star selections in 16 seasons. I never saw him play, so I don't know.
He played both ways for his first few seasons and was an all-star on offence as well as on defence those years.
Iron Men Football not may players could do that now.
The Game is not a Game of Specialists
My money is still on Joe Montford for best Cat D-Lineman
3 time CFL defensive player of the year
26 sacks in 1999...that is crazy!!!
157 sacks in 141 games
I have Grover second.
A good debate. All great players.
I'd say:
#1 John Barrow
16 All -Star selections in 14 seasons on both sides of the ball.
CFL Lineman of the Century... see cfl.ca
9 Grey Cup appearances, 4 wins
#2 Grover Covington
CFL all-time sack leader
#3 Joe Montford
3-time CFL sack leader
#4 Angelo Mosca
#5 Mike Walker
I`ll say this about Mike Walker he was one of the nicest if not the nicest player to talk to I ever met and yes he was also a great great player . Praise from a great player like Vercheval shows you that he was respected throughout the CFL.
Vercheval played pro for over ten years, two in the NFL. He played against a lot of good players. So I saw it as a real compliment to Mike Walker.
We had a similar discussion here recently re Montford and Covington. Mike Walker was a tremendous defensive tackle whose collaboration particularly with Covington made both players better over a long period of time. I agree with the assessment made re John Barrow. The record of all-star nominations and championships he enjoyed speaks for itself. Barrow and Henley are just that step above in terms of overall honours. We often forget just how fortunate our fanbase has been in seeing all these outstanding players, even if the team's record over the last generation has often been difficult to swallow at times.
The sticking point for me right now in these best-ever discussions is that Earl Winfield is still not enshrined in the Canadian Football Hall of Fame, but I digress.
Oski Wee Wee,
Mitchell Price is almost always forgotten but with him, Walker and Covington the three formed the core of that D-line at its peak from 83-86
Granted…and we cannot forget Rod Skillman in that mix either. Good times when the Cats D had teeth!
Oski Wee Wee,
One guy that we have never replaced was Mike Philbrick.
He was dominant in the middle.
Not sure why they would vote for the CFL lineman of the century in 1967???
Montford was not even born yet!
I've seen them all blackandgold, and although I believe that the cream of the crop for D linesmen
has been mentioned in this thread, I think you hit the nail square on the head.
John Barrow was wonderful, but he played in a very different era when the run was accentuated by every team. Linemen were much lighter than as well, so we end up comparing apples and oranges.
To me, Joe Montford had it all; speed, agility and killer instinct.
Covington, Walker and Mosca, I would consider to be equals.
Others mentioned in this thread, although very good players, really don't rate IMO, when we are discussing greatness.
1867...you know, that Confederation thing...1867-1967 is a century ...damn I want training camp to start! 
Oski Wee Wee,
