Remember that for the first few seasons, the focus is mainly on the running game, so a WR with some strength and blocking will help more than one with speed/agility. Plus CB's will probably have low strength and no blocking, so you won't need to raise those much higher than 30 the first couple of season. Also, with a decently high strength, your WR will be able to break a few tackles and be a better short yardage possession receiver.
I do not believe you will handicap your WR at later levels doing this because you would slow build the 1st season and thus it would bring you to around the same level as a normal, non-slow built WR at later levels, plus you will help your team more on runs as you can block better.
Ever heard of shed block?
You don't need the SA to shed a block.
Defensive players with higher agility will swim around blockers; a block is never engaged, thus no amount of blocking or strength will help you if you can never get close enough to the player. A CB in a 13 cap league will typically have first if not second capped agility. You will rarely see your blocking WR, who sacrificed all of his automatic leveling for nothing, engaging a block. On the rare event that he does, a FS, SS, and likely 2 of the 3 LBs will still be there to tackle your rusher. All you've done is make your WR completely useless and the team facing you can easily scout bars and place their crappiest level 9 CB against you the whole game because they know he won't let up any yards.
If that wasn't enough the second paragraph quoted is just incorrect. Slow building will not make up for points lost to majors. The entire premise of slow building is training your majors up early so you can cap them earlier in your level progression and benefit from an increased amount of automatic level gains to them.
You can make your strength/blocking WR idea work, but you have to raise majors first, minors second, then other skills for best SP value in the long run.
WRs:
Major Skills – Speed, Agility, Jumping, Stamina, Vision, Catching
Minor Skills – Confidence, Carrying
Other Skills – Strength, Blocking, Tackling, Throwing, Kicking, Punting
Of the major skills, these are useful to blocking: Speed, agility, stamina, vision
Minors: Confidence
Other: Strength, blocking
Therefor the best training pattern for a -blocking- WR would be:
Speed/Stamina
Stamina/Agility
Agility/Vision
Vision/Confidence
Finish up anything that isn't in the desired range with normal training
Strength/Blocking
